Viewers first witnessed Colt's tumultuous marriage to Larissa Dos Santos Lima, and after multiple domestic violence arrests, Larissa and Colt finalized their divorce in April 2019. Colt began dating Jess Caroline on spinoff 90 Day Fiancé: Happily Ever After? and even discussed starting a family with her—yet all the while Colt was unfaithful with "friends with benefits" partner Vanessa Guerra. Now, it seems like Colt is a changed man and ready to settle down once and for all with longtime love Vanessa.
"My mother and I have been very close throughout my entire life, and she's very much involved in my love life," Colt tells the camera. "It's been a strain for sure."
Colt explains that he was homeschooled through high school which made him even more dependent on his mom. "I do feel like being homeschooled kind of sheltered me in some ways, especially dating," Colt reveals. "I was a late bloomer in life."
But he's more than made up for it with his current Casanova persona. So has he finally been able to shed his Lothario light?
"With Vanessa, I feel like there's something different and I don't know if I can find it again," Colt questions.
Colt shows his mom an engagement ring wrapped in a purple bandana. "I'd like for your blessing to ask Vanessa to marry me," Colt tells Debbie.
"Are you out of your f––king mind?!" Debbie laughs. "Is she ready? Are you ready? What's the rush?"
While Debbie didn't hold back voicing her skepticism over Colt's exes Larissa and Jess, she is a fan of Vanessa—which makes it difficult for her to let Colt pop the question.
"I love Vanessa. I think it's wonderful that they're in a good place, but Colt's impulsive decisions aren't good," Debbie says in a confessional. "After five days he proposed to Larissa which he found out was a huge mistake. I think this relationship has a lot more going for it, but I think it's a little too early...I think it could destroy it."
So will Colt actually propose? Check out the shocking exclusive clip above to watch Debbie warn Colt!
