Jenelle Evans isn't the only one scared for her children's "well-being." Her ex, Nathan Griffith, has had some concerns about her situation as it relates to their 5-year-old son Kaiser as well.

Sources close to Griffith revealed to TMZ that relieved that Jenelle has finally left her estranged husband, David Eason. He apparently was worried about the safety of Kaiser due to Eason's "violent and disturbing behavior," as the outlet put it.

Overall, Jenelle's ex-fiancé believes she is a good mother, and, despite fighting for custody of their son, he is content with Kaiser staying with her, according to the source.

It's been a whirlwind since the former "Teen Mom 2" star announced she was separating from Eason. Since the Oct. 31 announcement, she's obtained a restraining order, which detailed several accounts of abuse she and her children have suffered at the hands of Eason.

"Because of his recent threats, his history of violence, his erratic behavior and his large stockpile of weapons, I am scared for my life and my children's well-being," she wrote in the Nov. 4 filing.

Amid all of the drama, there are also rumors swirling that Jenelle could return to the MTV reality show after she traveled to New York with her lawyer the weekend before her split from Eason.

"[A higher up] from MTV contacted Jenelle and requested a meeting with her," an insider shared. "They kept telling Jenelle that she is still under contract and that they wanted to talk to her about possibly returning to the show."
