For some bizarre reason we cannot even speculate, Jon's girlfriend Hailey has gone public and says Jon is emotionally abusive toward her. He gets angry at her, has tantrums, he lies, and is "mean" to her. But, she says, she still loves him and will still stay with him. Sounds like domestic violence to us. DV does not have to involve physical touching. It can be emotional as well.
