For example they picked up dinner plates and threw them across the room and they hit the wall on the other side and broke as well as putting a hole in wall and while doing this they yelled and screemed.
Oh gosh I'd dump the guy and leave. I wouldn't put up with behavior like that. I want to date a levelheaded adult who knows how to handle his emotions -- not someone who's violent and throws temper tantrums like an over-sized 3-year-old.
If I still cared about him on some level and felt like he needed real help, I'd try to contact his parents (if he's close with them) and give them a run down so that they could potentially help him through his issues.
I would dump him. He needs to take those anger management classes but I'm not going to stand by and watch until I get hit. I'm not going to wait around for him to potentially get better and get hit in the process, I'd rather date someone normal from the start. Who doesn't break things out of anger.
Well i admit i kinda do that sometimes but no with plates or anything dangerous. And i dont go all psycho and break things, just sometims when im really mad i. pn that one second, i throw dont like a shirt lol
