WATCH: Jenelle Evans Rethinks Fighting For Custody Of Jace During Explosive Fight With Nathan Griffith On Teen Mom 2

The honeymoon stage of Jenelle Evans and Nathan Griffith’s engagement didn’t last very long!

In a preview clip for this week’s Teen Mom 2, Jenelle and Nathan get into their most explosive on-screen fight yet. The jaw-dropping blowout even forces Jenelle to rethink fighting for custody of Jace against her mother Barbara.

The drama started when Nathan made Jenelle late for her appointment with her lawyer over the custody battle.

“I’m going to be late,” Jenelle said as her fiancé finally got into the car. “I’m so pissed off dude. My day is already f—king ruined.”

In an effort to avoid fighting, Nathan walked back into the house. But that didn’t stop Jenelle from continuing to fire at her beau!

“Let’s just go,” she begged after following him inside. “I have an appointment Nathan. This means a lot to me. This is for my son.”

Jace’s soon-to-be stepfather responded, “Your son, yup, not my problem. We are done Jenelle. You’re a b—tch!”

Nathan’s comment made her question her decision to get full custody of her first child. “I don’t even know if it’s worth it to even get him back because if he’s going to come home to this, Kaiser is already going through it,” she said of their one-year-old son.

But that wasn’t the worst of the fight, as things got even more heated once Jenelle told her fiance to “stop acting like a b—tch!”
