You aren't forced to do anything. If he's abusing you now it will only get worse. You do not ever have to live with someone that abuses you. Walk away now before he hurts you.
You just tell him you can't live life with someone that's abusive.
I may be forced to make decision to leave my boyfriend. He was verbally abusive to me more than once, Sunday, got angry and slammed out the door and slammed his car door. I feel I don't like him anymore. How do I tell him?
Discuss your feelings about his anger issues and how he displays his anger. Just tell him that you can't take it any longer , that you will no longer be his proverbial punching bag and it's done. This time you are slamming the door.
However you tell him (and I hope you DO tell him) it needs to be in a public place. If he gets mad like this I don't know what breaking up with him will cause his emotions so PLEASE do it in a public place, not isolated away from witnesses..... He will be less likely to touch you or act stupid if there are potential witnesses.
