We saw Jenelle and her baby daddy, Andrew, on '16 & Pregnant', but we haven't seen the guy since Jenelle questioned his paternity on a recent-ish episode of 'Teen Mom.' As Babs would say, Andrew's a LOOSA and not a good father, so we think the fact that they're no longer together is probably for the best.
Then, Kieffer happened. Kieffer and Jenelle met at a beach party shortly after he dropped out of high school, and we knew from that very moment on season 1 of 'Teen Mom' that he was bad news. More on that later though.
In between Jenelle's on-and-off ness with Kieffer, she hooked up with Gary Head. Most recently, Gary and Jenelle were engaged on season 4 of 'Teen Mom 2.' He even bought her a puppy! But soon afterwards they broke up and then were going to court for charges placed against each other. Yeah. Needless to say, these two did not make it work.
As we saw play out on the most recent season of 'Teen Mom 2,' Jenelle went crawling back to Kieffer after her huge fight and physical altercation with Gary. They seemed to be better and Kieffer sorta kinda seemed to be getting his act together (and he even had a hug with Babs! Huge moment), but as we learned on the reunion show, Kieffer tried to get Jenelle into heroine and almost killed her while doing it. So. Yeah. Dunzo.
Courtland and Jenelle didn't officially start dating until this past September, even though they knew each other for years before that. Then, in December 2012, they got married and were in the midst of a divorce just months after that. Now? We don't think they're together anymore, but they tweet at each other all the time and seem to still have some feelings there. Who knows anymore.
During Kail's episode of '16 & Pregnant,' it actually seemed like these two had a chance at making it work. But once Isaac was born and Kail moved into Jo's mom house, all hell broke loose and these two broke up. They're better now at getting along and co-parenting though, so thank goodness for that.
Kail moved out of Jo's house shortly after she started dating a new guy, Jordan, whom she met at her job. They got pretty serious and clearly Isaac was into him, but a few months in, Kail cheated on Jordan with Jo. Jordan took her back but then they broke up again for good shortly afterwards.
Then, came Javi. The One. Javi and Kail met through a mutual friend and got married in September after about a year of dating. Now, she's an army wife and they're expecting baby number two in the fall. Congrats, you guys!
It's a known thing that Leah and Corey got pregnant (with twins!) after only a few months of dating. These two were doomed from the start, but they tried to make it work by getting married really quickly. The divorce was quick too. Now, they're co-parenting well and are both happy in other relationships so good for them.
Leah actually dated Robbie before Corey and '16 & Pregnant', but he came back into the picture shortly before Corey and Leah's wedding when Leah cheated on Corey with him. Think he's what eventually broke Leah and Corey apart?
After things with Corey were officially over, Leah settled down with Jeremy, whom she met on Facebook. Wait, JK. She had a love triangle going with Corey and Jeremy for the entire season 4 of 'Teen Mom 2.' But eventually, she and Jeremy got hitched and now they have a baby girl together. Yay them.
And we saved the worst ex boyfriend for last—Adam Lind. Adam basically was an absentee father for most of Aubree's early life, but somehow he still managed to keep going back to Chelsea and screwing with her head (and other things). They're dunzo now and he's got another baby on the way with someone else, but Chelsea's still single and officially done with Adam. Hallelujah.
