Evans and Griffith parted ways in July after rumors surfaced regarding his relationship with Jessica Henry. However, according to Griffith, his relationship with Henry didn't get serious until after he split from Evans. During an interview with Radar Online in August, Griffith claimed he broke of his engagement with Evans due to her drama-loving behavior.

"I was with Jessie before and I'm with her again. Jenelle and I are not together and I did not cheat on her. She knows we have been broken up," Griffith explained to the site. "Jenelle is crazy, but we have a family together and I believe in second chances, so I gave it to her. I have a big heart. But now I am done. I can't go back to all of that."

"She kept telling me 'I'm going to ruin your life,' and I just don't care anymore," he claimed. "I don't care. I can't take it anymore."
