Clearly the two of you are not good together because you got into an altercation that involved you slapping him and punching him — your headline that you hit each other “once” isn’t very truthful. It sounds like you had one full out altercation and it affected you both negatively.
You need to get a handle on your ability to control your impulses because slapping and hitting a guy — or a girl or a pet or anyone or anything — is going to follow you from relationship to relationship unless you get a handle on this issue. It’s okay to get angry — and there are many times when it’s a healthy and appropriate response. However, hitting someone because you’re angry is never appropriate. If you feel yourself losing control, leave the situation or the room or the venue entirely. Taking yourself out of situations that lead to violence is a surefire way to help solve the problem.
