Will 'Teen Mom 2' Star Jenelle Evans' Broken Engagement Impact Her Custody Case?

Evans and Griffith ended their relationship at the end of last month, and days later, Griffith went public with his new girlfriend, Jessica Henry.

“Jenelle has been crying and been depressed about Nathan, but she’s been working out a lot and she stayed with her friend all this past week and has been trying to relax,” the source explained.

As for what happened during the alleged altecation, the source claimed Evans invited Griffith back to the home they once shared to pick up his belongings. However, instead of coming alone, Griffith showed up with Henry in tow. Still, the source insists Evans didn't mean to cause injury to the woman.

“Jenelle did not intentionally throw a glass at her,” the insider explains. “It slipped out of her hand and then Jessica picked it up and threw it back at her. Jenelle got upset. Jessica said words to her and Jenelle was confronted. Nathan called the cops. The two of them will do whatever they can to make Jenelle look bad.”
