I slapped my girlfriend and kicked her after she cut me off.
Why would you hit your girlfriend after she cut you off?
Because my girlfriend is a disgusting whore that I no longer want to be associated with.
Its understandable that you are angered that she cut you off, but she doesn't deserve to be abused in any way. Keep that up and you will be in jail if she hasn't already tried to press charges already. It can ruin your life on many levels if you hit people.
Maybe I'll do it again then.
You should never hit a girl regardless of what she may do to you. Unless you feel your life is in danger, hitting a girl is just not tolerated in our society.
