Oh, my. I read "hit woman during road trip" and thought it was a hit and run.
She slapped him first. Sauce for the goose and all that. I probably would have done the same had he lifted me (assuming he didn't get a hernia), but I would expect that if I hit someone that I'd be getting it back shortly.
If he gets charged, she should too as she hit first.
No she didn't, lets get real here. He assaulted her first by grabbing her and lifting her into the air.
It'd be one thing if he just said some flirty type stuff to her and she hit him, but he physically assaulted her in the middle of a fight and that is is prompted her to slap him.
