'Teen Mom 2' Jenelle Evans Mentally Abusive Relationship With Nathan Griffith: MTV Dad "Has Her So Controlled, It's Sickening"!

Teen Mom 2 star, Jenelle Evans, may be trying to make it seem like her relationship with fiancé, Nathan Griffith, is doing well, but behind closed doors, it seems like the MTV couple is on their way to a train-wreck breakup.

"Nathan has her so controlled, it's sickening," a source told Radar Online. "He's a control freak. It's crazy. He controls her life."

"He won't even let some of her relatives see the new baby as much they want," the source continued. "They're constantly fighting."

Their toxic relationship also includes constant arguments about whether the two are cheating on each other.

"He loses his mind over every little thing that Jenelle does," according to the gossip site. "He's jealous, but HE's the one talking to other girls and then he gets mad when Jenelle calls him out."

 My biggest supporter, my best friend, my lover, my everything. Through thick and thin U were and will always be there for me. I love u so much words can't even describe. If one day we could just switch bodies, only then U will then understand.

Part of the frustration for those close to Jenelle is the fact that Nathan doesn't have a job and using her for the reality show money. "He is not doing anything to contribute to their lives and is totally just living off of Jenelle," the source said. However, the fault ultimately lies with Jenelle since it is her choice to stay with him. "It's a pattern for her," Radar reported. "That's the type of relationship she goes for." As MStars News reported, Jenelle and Nathan were caught in a firestorm after VH1 star Stevie Ryan disclosed private messages the reality dad sent to her about the MTV star. These included shocking revelations that Jenelle wanted to hurt herself and blame her baby daddy to the police.

"Can't believe I'm telling you this but the other night I was trying to walk away and Jenelle started putting holes in the wall kick the bathroom door in because I told her it was over," he wrote. "I was about to call the cops because I said my son is sleeping stop yelling and she said if I did she would tell them I hit her and she would put marks on her."

Do you think it's healthy for Jenelle and Nathan to stay together even though they have a son together?
