'16 And Pregnant' Sneak Peek: Will A Fight Over Finances Tear Two Young Parents Apart?

Aleah storms out on her boyfriend -- and their baby -- during a fight over traffic tickets.

Financial problems can cause any relationship to falter, and on tonight's episode of "16 and Pregnant," we'll meet Aleah, who gets into an ugly fight with her daughter's father, Shawn, about him owing money for unpaid traffic tickets.

In the sneak peek below, we see the dispute quickly escalate as the young couple battle over the mounting fines. Aleah is understandably upset by her boyfriend's irresponsible behavior, but Shawn’s mom, Angie, tries to downplay the issue.

"It's gonna happen, you guys are gonna have money problems probably the rest of your life," she tells the new parents.

Aleah senses there's no use in arguing with both Shawn and his mother, and starts to gather her things to leave, but Shawn's temper flares up.

“I don’t need a second mom, I need a girlfriend!" he shouts at her. "I need a mother of my children, not of me.”

After Aleah unsuccessfully tries to explain that the money could have been spent on Baby Peyton, Shawn tries to reason that "that's what tax time's for."

Exhausted and defeated, Aleah says she needs to move out, but Shawn and Angie won’t let her take Peyton. “You better go find something to do to cool your f**king head because I’m keeping my daughter,” Shawn says, antagonistically. “[Peyton’s] not going nowhere.”

Watch the video, and tune in to “16 and Pregnant” tonight at 10/9c to see if Aleah and Shawn can put their money issues aside and make things work for their little girl.
