In the trailer for MTV's "Teen Mom 3" (above) new mom Alex is struggling to pay the bills working three jobs while her on-again-boyfriend Matt can't hold down one. To make matters worse, she suspects he's been using drugs.
"You look like you're on something. I don't want you around her!" she tells him of spending time with their daughter Arabella.
Briana is also hesitant to leave her daughter with her baby's father, Devoin, especially when she has so much support from her friends.
"I'll be damned if I let her go with you," she tells him, later adding, "Nova has three moms. I don't need Devoin!"
Katie is taking courses at a local community college while raising her baby, but she can't help questioning how her boyfriend Joey really feels about her.
"Why can't you love me like I love you?" she asks in a fit of tears.
As for Mackenzie, well, she's convinced her life is in shambles. "I feel like I've already made all of these mistakes," she says.
