“It didn’t work out," Ed says on the show of his previous marriage.

Before coming on 90 Day Fiancé, Ed was married to another woman named Sandra, and she’s the mother of his daughter, Tiffany.

“She’s the best thing that I have created on this earth,” he says of his daughter.

Ed admitted that his previous marriage only lasted two years. Why? 

“Because I was unfaithful,” Ed says on the show of his relationship with Sandra. “It was just a stupid mistake.”

He goes on to explain that despite his failed marriage, his daughter is what has kept him going all of these years — and it’s because of her that he avoided dating for so long. Since his divorce from his ex-wife, Ed admits that he hasn't dated much, and he believed he was never going to marry again. Rose was his first serious relationship in years. 

It wasn't his previous infidelity that led to Rose's decision to leave Ed, though. While there are a lot of reasons she could've decided to leave — like Ed's criticism of her unshaven legs or bad breath, or his borderline controlling behaviors — it was really the way he treated her on-screen that led to her decision to leave.

"How dare you embarrass me in front of millions of people," she said in an Instagram live about their split. "People, don't believe him. He doesn't really care about me. He just wants to be famous, that's why he's doing that."
