You're not going to believe this and we strongly hope you're sitting down, but Jenelle Evans and Nathan Griffith have reportedly broken up.
Yes, again. What led to split #5,489?
The Teen Mom 2 star reportedly labeled him cheater, but Griffith - who just got back together with Jenelle earlier this summer - denies this.
He also says she is “crazy!” FWIW.
Evans tore him a new one last weekend for cheating with Jessica Henry, which he says is not the case ... because he and Jenelle broke up.
Yup, it was already a done deal by the time she called him out ... which took place only a few weeks after she was wedding planning with Nathan.
"I was with Jessie before and I'm with her again. Jenelle and I are not together. I did not cheat on her. She knows we [broke] up," Griffith said.
We would hope so.
"Jenelle is crazy," he said. "But we have a family 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. I don't care. I can't take it anymore."
Griffith blames MTV in part for the turbulent couple's issues, saying, "MTV feeds into her ego! They want her to get upset about things."
"When I got arrested the crew was there and they knew that I wasn't hitting her. They just don't care," he claimed. "That's messed up."
"Jenelle is addicted to drama."
Further explaining his timeline of events, he adds, "We did get back together for a while. But then we broke up again and I have been with Jessie."
"Every day now. Jessie and I were broken up for a little while but are back together now. I didn't cheat on Jenelle and she knows it."
Despite all the drama between them, Griffith told Radar that he is willing to move forward amicably and remains concerned for Evans.
"She needs help," he said. "She really does."
No clue what he's referring to ...
