Teen Mom 2's Jenelle Evans is ready to change her ways.
In an exclusive sneak preview from Tuesday's all-new episode, the reformed partygirl -- mom to Jace -- calls a truce with her mom, Barbara Evans.
The 19-year-old's relationship with her mom has vastly improved to the point that she's ready to sign over temporary custody of her son.
"When you kicked me out, I realized I can't take care of Jace on my own yet because I can't even support myself," Jenelle, who once threatened to punch her mom in the face during an explosive fight over custody, admits. "I am going to start making changes, but I'm just going to sign over custody because I don't want to go through [court hearings] just to get the final decision from a judge."
Barbara, 57, applauds her daughter's decision.
"I hope this is a new beginning," she tells Jenelle. "Let's not fight so much any more."
As the pair makes amends, Jenelle largely credits her new boyfriend, Keiffer Delp, with keeping her calm.
"Now that I look back, I think it was stupid to freak out that way. I've grown a lot calmer since I've met this guy," Jenelle tells UsMagazine.com. "Now, when my mom starts yelling at me, I won't yell back. I haven't raised my voice at her in a long time."
