He should've never posted that hand on the ass shot.
That being said, it is curious how she has tape of fight, but no pictures of bruising, wrecked apartments, broken stuff, etc... if he was such a terror being around. Tape shows a dysfunctional relationship, but who knows how bad it got. Edit - also if the cops are coming out for a violent domestic, someone is getting arrested, but nothing happened here. I wonder how they saw it.
The mental abuse angle I don't give a shit about, because who knows what it was. The standards for that sort of thing have dropped way down over the years. If he called her a cun-t, bitch, worthless, etc... during a heated fight, it's what happens sometimes. She could have left years ago.
I won't excuse the cheating, but they're 20 somethings in the fitness industry. Faithfulness isn't something that happens there.
50/50 on if his career survives this, but it's taken a big hit.
