Teen mom 3 sneak peek: brittany is fed up and ready to fly the dejesus coop

The members of the Dejesus family support each other implicitly, but even the tightest of troops have their off days. Briana’s sister, Brittany, has been championed by both Bri and her mom, Roxanne, for being the best aunt ever (complete with trophy!), but in this sneak peek of the next “Teen Mom 3” episode, the girl who has sacrificed so much to help her sister raise Baby Nova seems to have finally had enough.

As the the family chats over a meal, Briana points out that her sister’s attitude has been foul all day. “I’m tired of having to deal with everybody else’s problems,” Brittany explains. “After Nova was born and all this commotion, I just can’t deal with it no more.” While Roxanne grows increasingly frustrated with Brittany’s bad mood, Briana tries to diffuse the situation, but to avail.

“I want to move away. It’s time that I flap my wings and fly far away,” Brittany says, to which Roxanne — in true Alpha mom form — calls her bluff. “You want to pack up and leave? You can get up and go,” she says.
