Jealousy can sometimes turn people into jerks, and on tonight's "Teen Mom" premiere, we got a sour taste of how Ryan may have felt about Maci's serious (and rather healthy) relationship with Kyle. To be fair, it must be extremely difficult to know that your child is starting to view another man--whom you haven't yet met--as a father figure, but that doesn't exactly excuse Ryan's rude text to Maci that asked if Kyle was "slow." Good thing Maci's so accustomed to her ex's immaturity that the comment didn't even phase her. In fact, she tells SuChin Pak in this clip from our "Teen Mom After Show" that she couldn't help but laugh at the ridiculousness of the question. "I think [Ryan] felt like Kyle was taking his place," she says. Check out the video below to hear more of her reaction to Ryan's "jealous" dig, as well as why she'd been waiting so long to introduce her past and present lover.
