Teen Mom 2 star Jenelle Evans lost custody of her son Jace to her mother Barbara years ago. Now she wants him back. Barbara is acting in the best interest of the little boy, with Jenelle acting in the best interest of Jenelle–something she’s very good at.

A recent episode of Teen Mom 2 found the mother and daughter at odds about the custody arrangement, and trying to work it out in mediation.

Jenelle Evans isn’t known for being reasonable. Her trips to rehab make it quite clear she’s in no position to raise a child.

Mediation didn’t pan out for the Teen Mom 2 star and her mom, meaning the next step–if Jenelle continues pursuing the issue–is a court case.

Following the unsuccessful mediation, Jenelle and Barbara met at a nearby restaurant to continue their conversation and to try to come to a mutual agreement.

“Court will be devastating. It might not be the answer you want to hear,” Barbara tried to reason with the Teen Mom 2 star. “You can’t just rip him out of everything he’s ever known.”

“I should have him full time, not you!” the Teen Mom, who has been arrested numerous times, said. “I’m the mom, you aren’t the father either. You’re just the grandmother!”

“This whole thing is about Jace! It’s not about you, it’s not about me!” Barbara insisted. “All I know is: Get your life together, then we gotta figure out what to do with Jace, but Jace is going to be very, very upset if he has to leave.”

While the two women conversed, baby Kaiser made a mess (yes, the Teen Mom 2 star has another child with fiance Nathan Griffith) and Jace was running around.

Jenelle Evans assessed the situation the two children were creating, an decided she couldn’t handle talking about custody issues at that moment.

“Oh poor baby,” a very exasperated Barbara said.

It is unfathomable to most reasonable people that this Teen Mom 2 star thinks she is better off taking custody of Jace than leaving him in the very capable hands of her mom–who has raised him since infancy.

If she can’t even handle the messes two children create in a restaurant, why does she believe she should have her first son returned to her on a full time basis?
