Kailyn Lowry and Chris Lopez
Kailyn Lowry and Chris Lopez are kind of unique in that we don't really know much about their relationship because they've both always said different things about it, and he refuses to appear on the show. We do know that they were friends in college, and that she got pregnant right around the time her divorce from Javi was finalized, and that Chris was just not interested in any of it. He missed doctor's appointments during her pregnancy, Kail said he had another girlfriend, and although he did show up when Lux was born, she later said that he got abusive just weeks later. Still, she's said that he's her first love (for real, she said that), and they did get back together for a few months before going back to hating each other. Then they got back together again, and so on and so forth. So ... yeah, it is and has always been a disaster.
Kailyn Lowry and Jo Rivera
Kailyn and Jo were horrible to each other when they were dating. Just really, really awful. Remember when Jo told her "You don't deserve to be outside enjoying the sun — you should be in a cave"? Way harsh. They've had their good times co-parenting Isaac, but things are often bad between them now, too.
Farrah Abraham and Simon Saran
Farrah and Simon dated for a while, and we think it worked out for so long between them because they had many similiarities -- they're both narcissistic and super thirsty for fame, mostly. But we have a hard time believing that Farrah is even capable of being in a healthy relationship, so their spot towards the middle of this list feels well-deserved.
Leah Messer and Jason Jordan
Ah, another love we thought might last ... not so much though! Jason was a bit older than Leah, but since she has three kids, one with a terminal illness, a lot of people thought that maybe his maturity would be good for her. As it turned out, her kids thought he was a creep and he was weird and controlling, so Leah dumped him. So long, sucker!
Cheyenne Floyd and Cory Wharton
Cheyenne Floyd and Cory Wharton are new-ish to the franchise, so while they share a child together, they were broken up by the time they began appearing on Teen Mom OG and we just don't know as much about them as we do most of the other couples. But they do seem to get along very well, and there's also always been a chance that they'll get back together. Like, they've never assaulted each other (that we know of), so for this list, they're pretty good.
Leah Messer and Jeremy Calvert
Jeremy Calvert was married to Leah Messer, and they share a daughter, Adalynn. He filed for divorce during her struggle with addiction, and since then, they've hooked up a time or two (or more). This is another couple that's difficult to pin down, because they were definitely terrible for each other, but like ... in a franchise with this much abuse, there are bigger fish to fry.
