A new group of couples at a crossroads head to Sin City in The Ultimatum: Marry or Move On Season 4. But what happens in Vegas wonât stay there, as relationship doubts, surprise connections, and hard truths lead to a life-changing decision: Will they get engaged or walk away forever?
Among the six couples are childhood crushes who finally got their timing right, business partners balancing romance and ambition, and one pair whose connection was sparked by a late-night DM.
But while love brought them here, it hasnât been enough to get them to the altar. For some, the uncertainty comes down to timing. For others, itâs about trust, shared values, or whether theyâre truly aligned on what marriage should look like. Over the course of the experiment, theyâll step outside their relationships and into trial marriages to gain perspective on what they want, what they need, and whether the future theyâve envisioned is actually the right one.
Get to know the six couples putting everything on the line in search of clarity, commitment, and their happily ever after. Then tune into their journey, streaming now.
Hayley and Blake

Blake
26
Head of marketing and operations
âStop trying to change the person you fell in love with.â
Capricorn
Blake loves a good plan â and an even better outcome. He considers himself a âresults-driven person,â which is ideal for working in his family business, but less so in a romantic relationship. The pair first met when Hayley was nannying his stepbrothers, but it took family wine night around a fire pit for sparks to fly. âI showed up, got a glass, and Hayley and I immediately had chemistry,â he says. The analytical counterpart to Hayleyâs emotional side, Blake feels strongly that the logical next step for them is marriage. While Hayley says she needs more time to move past feeling emotionally neglected early in their relationship, Blake is wondering how long is too long to wait. âI donât want to look up three years later and still be trying to earn forgiveness,â he says.

Hayley
23
Marketing specialist
âLove is not enough to build a healthy marriage.â
Sagittarius
Hayley likes to say she and Blake are fire and ice. Passionate and unapologetically emotional, sheâs looking for more vulnerability from Blake as they enter the experiment. Growing up, Hayley admired relationships where both people seemed considerate of each other, communicated openly, and enjoyed doing life together. âThere was a sense of partnership and mutual respect that always stuck with me,â she says. Blake caught Hayleyâs attention when she briefly nannied for his stepbrothers. Well, more accurately, she caught his. It took a month of persistence before she finally agreed to a date. Today, the pair has formed a relationship full of laughter, adventure, and friendship. One of Hayleyâs favorite things about Blake is his ability to make her laugh â especially when he breaks out his dance moves. âWe can always have a great time and have so much fun,â she says. But now she wants to see if Blake is willing to open up more emotionally before she can agree to forever.
Ashley and Killian
ULTIMATUM GIVER: Ashley

Ashley
26
Content creator
âPotential is one of the most dangerous things to date.â
Taurus
Ashley has always believed in happily ever after â just not the fairytale version. âIâve dreamed of marriage my entire life, but not because I care about a wedding or a title,â she says. âI genuinely love building a life with someone.â Ashley strongly values reliability, especially after watching her parents build a life rooted in loyalty, respect, and unwavering partnership. That dream felt within reach when she met Killian more than 14 years ago on the competitive cheerleading circuit. Today, the couple shares a home and two fluffy Pomeranians. Heading into the experiment, Ashley isnât searching for a new love story. Instead, she hopes the process will give both of them clarity about their future together. However, as a self-described âdaddyâs princess,â Ashley wants her father to give his blessing to Killian before he pops the question. Time will tell if Killian can earn her dadâs trust before Ashley walks away forever.

Killian
29
Real estate agent
âŠ
Aquarius
Killian and Ashleyâs love story started when they were both teens on rival cheerleading teams. A chance reunion during Ashleyâs girlsâ trip to Miami brought them back together. When Ashley decided to make the move to Miami full time, she took a leap of faith and asked Killian to move in with her â even though they werenât technically dating yet. Four years and two fur babies later, the couple relocated to Houston to be closer to Ashleyâs family. Killian says he received her dadâs blessing to propose, but Ashleyâs father rescinded his permission after a âfamily altercation.â Ashley is eager to start their lives as a married couple, but Killian doesnât want to get engaged unless they have her familyâs full support.
Casey and David
ULTIMATUM GIVER: Casey

Casey
34
Entrepreneur
âCouples should follow each othersâ location.â
Sagittarius
Casey has no shortage of proof that David loves her. She has three promise rings from him already, and â as she likes to joke â sheâs ârunning out of finger space.â At this point in her life, sheâs ready to have children, and for her, that starts with marriage. A hopeless romantic at heart, Casey has always dreamed of the kind of lasting partnership she saw modeled by her grandparents. But that doesnât mean she needs grand gestures to feel appreciated. In fact, her favorite date night involves comfortable sweats and a movie. Itâs the small moments that mean the most to Casey. One of her favorite traditions is their secret â4Lâ signal. Whenever theyâre busy and cross paths during the day, David flashes four fingers and then an L with his hand. âItâs short for âFor Life,ââ she says. âWe love each other for life.â

David
33
Pro basketball player; business owner
âTrust, respect, and consistent effort matter just as much as love.â
Sagittarius
David isnât afraid to take a shot. After all, the pro basketball player first connected with Casey by sliding into her DMs â and heâs been all in ever since. David loves to travel, ideally exploring a new city with Casey by his side. When theyâre not on an adventure, the two co-own a drug-testing clinic, blending business and romance as they build a future together. While David doesnât doubt how much Casey means to him, commitment brings up a deeper fear: What if he devotes himself fully and she leaves someday? âI donât take love or commitment lightly, and when Iâm invested in someone, Iâm willing to put in the work to make things last,â David says. Like Casey, his grandparentsâ relationship still inspires him, and he hopes to replicate the same qualities in his own partnership. âNo matter what challenges came their way, they always seemed to face them together,â he says.
Monica and Luke
ULTIMATUM GIVER: Luke

Luke
30
Restaurant manager
âYour marriage should be the most important relationship in your life.â
Capricorn
Luke has been crushing on Monica for most of his life. The two met when they were just 14 years old, growing up down the street from each other in a close-knit neighborhood. Monica may have friend-zoned him at first, but Luke is nothing if not persistent. That tenacity has come in handy in areas beyond his love life, as he balances studying to become a firefighter while working as a restaurant manager. âI make her breakfast before work, open her car door, carry the bags, block the sun, I do whatever I can to make her life a little easier,â he says. While Monica feels there are important milestones to reach before getting engaged, Luke believes they can accomplish those goals together as a married couple â which is why he issued the ultimatum. âMonica is the best thing thatâs ever happened to me,â he says.

Monica
28
Head of operations and retail for a swimwear brand
âForgive your partner ⊠a lot.â
Libra
Monica considers herself high maintenance, but thatâs just because she knows what she deserves. Ambitious, driven, and always striving for the best, she wants a partner who can match her energy â and finances. Despite her love for Luke, Monica isnât convinced theyâre ready for marriage. While sheâs never doubted his feelings for her, she questions whether heâs prepared to step up as the husband she needs. âI believe there is so much more to a successful marriage than love, and Iâm not confident weâre there yet,â she says. Monica and Luke grew up in the same neighborhood, and though they never officially dated, the two spent summers flirting before eventually sharing Monicaâs first kiss. âHe was always my biggest crush growing up,â she says. After college, the pandemic brought them both back home. âOur connection was pretty instant,â she says.
Jessica Grace and Edris
ULTIMATUM GIVER: Jessica Grace

Jessica Grace
35
Real estate agent
âŠ
Gemini
Jessica Grace is ready for her forever. A bilingual realtor and former NBA dancer for the Charlotte Hornets, she brings energy to every room she enters. One thing she wonât compromise on? Selfishness. For Jessica, a partner who puts themselves first is the ultimate deal-breaker. Sheâs looking for someone ready to build a life as a team â and believes sheâs found exactly that with Edris. Their first chance encounter turned into a connection neither of them expected: Jessica made the first move in a hotel lobby, but Edris quickly reciprocated with an invite to spend the Fourth of July together. By August, they signed a lease together. Although she and Edris both want children, Jessica is crystal clear: marriage comes first. In fact, Jessica says she was âready to get married yesterday.â

Edris
38
Actuary
âOpposite-sex friendships can exist, but there has to be transparency and respect.â
Pisces
At first glance, Edris may seem serious, thoughtful, and measured. Still, he insists thereâs another side to him that people donât always see. Edris is goofy, playful, and loves to laugh â especially when Jessica Grace breaks out her infamous Hunchback of Notre Dame impression. The two have been together for over two years, but differing perspectives on boundaries became one of the biggest hurdles in their relationship. âI wasnât sure Jessica and I shared the same values around boundaries, respect, and emotional safety in a relationship,â he says. He hopes this experiment will offer clarity. 16 years of sobriety have shaped who Edris is, teaching him that love isnât just about chemistry. âItâs also about daily choices, accountability, and becoming the kind of person someone can actually count on.â
Alex and Jebin
ULTIMATUM GIVER: Alex

Alex
23
Hairstylist
âReligion matters.â
Aries
Despite standing a full foot shorter than her partner, Alex has never had a problem making her presence known. The hairstylist knows what she wants and will work until she gets it â including when it comes to marriage. Alex met Jebin working at a local grocery store in Chicago. After a late night at work, the two shared an Italian ice and a first kiss. Alex fell for Jebinâs goofy sense of humor, spontaneous singing performances, and dance moves that never fail to make her laugh. Still, after six years together, Alex is tired of waiting in limbo and issued Jebin an ultimatum: propose or sheâll move on. After the trial marriages, the experiment will allow Alex and Jebin to live together for the first time. A bit of a homebody, Alex says her ideal date night involves takeout, a board game, or getting creative with a shared craft project.

Jebin
23
Hedge fund manager
âYou have to ask your girlfriend to be your valentine.â
Leo
Jebinâs love story with Alex started in the checkout line of a grocery store. Now a hedge fund manager, Jebin is a long way from the teenage cashier who would ask the cute bagger for help. The two have shared a lot of laughter over the six years theyâve been together, but the challenges stemming from religious and cultural differences have begun to pile up. Jebin says his parents donât support his relationship with Alex because sheâs not of Indian descent. âI wish my family were more accepting of her,â he says. He fears choosing Alex means losing his family in the process. Beyond testing his relationship, the experience marks a major personal milestone: living outside of his parentsâ home for the first time. As he faces newfound independence, Jebin must determine whether heâs ready to build a future on his own terms.
