Elizabeth claims her ex-husband, Brian, is “nothing short of evil,” and makes it difficult for her to have a relationship with their 14-year-old son.

“My ex-husband is brainwashing my son,” Elizabeth claims. “My son believes all of the negative things against me. He feels, like, by loving me, he’s betraying his dad.”

Elizabeth also claims that Brian has been abusive toward her and now she has PTSD, which led to a suicide attempt and then Brian being awarded full custody from the time their son was 2 until 12.

“Brian is very dangerous. Brian was arrested for stalking his ex-girlfriend, and that’s how I got custody,” Elizabeth claims. “I am concerned that Brian might get mad at me and then tell my son, ‘Sneak in on your mom while she’s asleep and kill her.’”

Brian, however, says he doesn’t need to brainwash their son because the boy can see for himself that his mother is a vindictive, unstable liar. He claims the only reason she got custody was because she and his ex-girlfriend lied about him, and now, their son acts out every time he is supposed to return him to his mom.

“I don’t believe Elizabeth is stable at all. Elizabeth overdosed we know of four times, and we believe there’s a fifth time that was covered up,” Brian claims. “At one point, she even threatened to kill herself and my son by driving off the road.”
