Jenelle Evans and Andrew Lewis
Yeah, we haven't had the pleasure of seeing these two much beyond Jenelle's 16 and Pregnant episode, but that doesn't mean we don't know how terrible their relationship was! He was quite a bit older than her, and he abandoned her almost immediately after she gave birth to Jace. He would periodically send poor Jace gifts, but like cardboard boxes filled with sketchy toys, so .... Andrew recently tried to come back into Jace's life, but it didn't go great. Andrew is awful.
Jenelle Evans and Nathan Griffith
Yes, Evans is in a league of her own with these winners. This one fathered her second child and is engaged in a never-ending battle for custody of Kaiser. Nathan is no prize himself, of course, what with his multiple domestic violence and DUI arrests, so that's tantamount to a war of attrition. Poor Kaiser. This list is not all Jenelle, we swear. Eventually, the couples improve somewhat.
Jenelle Evans and Kieffer Delp
Jenelle Evans and Kieffer Delp weren't much better. It was during the Kieffer years that Jenelle turned to hard drugs, and she got arrested a whole bunch of times then, too. Delp, to his credit, did give us Barbara Evans' hilarious pronunciation of his name during her frequent rants to Jenelle at least. YA HIGH! YA BOTH HIGH! I SEE YOU WIFF KIEFFAH!! Classic.
Amber Portwood and Matt Baier
Where do we even begin with this disaster? Amber Portwood's former boyfriend/fiance/Deadbeat Dad Extraordinaire Matt Baier had the dubious distinction of being SO BEYOND BAD for her that we're ranking her relationship with her high school boyfriend - who she beat on camera - much higher on this list. It's frankly amazing that Amber and Matt lasted as long as they did, considering how he hit on other Teen Mom cast members, had betweeen 7-9 kids (maybe more, the world will never know) from previous relationships, was never fully honest about his addiction issues, is 20 years her senior, and failed a lie detector test.
Maci Bookout and Ryan Edwards
Ryan Edwards could definitely be the worst dad in the entire franchise, but if we're focusing solely on relationships, his with Maci Bookout was ... well, not the worst, but still not good at all. Even from the very beginning, he never seemed to love or respect her -- we all remember when he made her climb out of his huge truck to check a tire when she was very, very pregnant with Bentley. He chose clubbing and hanging out with friends and basically everything else over being there for her and his son, so it was wonderful to see her finally give up on her dreams of a happy family and face the reality of how much of a deadbeat he really was ... and still is.
Farrah Abraham and James Deen
We know. Farrah Abraham and James Deen were not in a real relationship, but that doesn't change the fact that she wanted us to believe she was dating this adult film star and that their high-production value quote-unquote sex tape was "leaked." Farrah's relationship with the truth has never been very strong. She insists to this day that she is not a porn star, despite starring with a porn star in a film entitled Backdoor Teen Mom, in which she takes ... you get the idea.
