sooooo

Honestly no one ever thinks their boyfriends or girlfriends would hit them, but it happens. He straight up told you he wants to. While I can oddly enough understand missing that type of relationship, him saying he wants to hit you is a huge red flag and needs dealing with.

Yes I think you should be worried. It's not normal to tell your gf that you want to hit them. Then having already been in that type of relationship... this is bad.

He could take up boxing or MMA if he really needs to hit something so bad. Honestly though, if he ever ever hits you (it doesn't matter if it was an "accident" and "he'll never do it again", leave the relationship. And do some soul searching to determine what you really think you deserve. Women can get stuck in an abusive situation if they don't think highly of themselves and believe that they deserve it. You don't. No one does. You deserve to be happy and to be with someone who respects you and cares about you too much to let you get hurt. Let alone be doing the hurting himself. MAYBE what he's really after is a passionate relationship. You can have honest, spirited debates without being violent. And you can have strong positive emotion and passion without abuse. Something to think about. 

He's literally telling U he wants to hit u. It's only going to get worse I promise u. No one wants to hurt someone they care about. Nor is he your father it is not his job to punish u. I would say leave now while u can. 

Uhhhh yes you should be worried.
