'Teen Mom: A Closer Look' Sneak Peek: Jenelle Explains Why She Left Home Without Jace

Blowups between Jenelle and Barbara are sadly common to the Evans household. On the most recent episode of "Teen Mom 2," a fight escalated to the point of Jenelle flying the coop and leaving her son behind. Tonight on "Teen Mom 2: A Closer Look," Jenelle will expound on why she finally called it quits with living under her mother's roof.

Jenelle recalls rehab therapy sessions, where she discussed the fights with her mom, in this sneak peek of tonight's sit-down with SuChin Pak. She tells SuChin she knew she needed to break the cycle of arguing with her mom in order to develop into a good mother herself. The most difficult part of living at home, she says, was feeling like a battle was always looming: "I take a walk, and I come back...she picks up where she left off. I'm like, 'What do I do? I'm stuck.'" Ultimately, following her therapist's advice to leave wasn't easy. "I wish [Jace] was old enough to see that I'm leaving to stop the argument--I'm not leaving just to desert him."
