My ex boyfriend came to my apartment unannounced and walked in on me with another guy 2 nights ago. What do you think I should do?
What did he do when he found the two of you together?
He started to yell at me and threw things at the guy.
If your ex came in without your permission, you have every cause to worry, particularly because he was also violent. Have you talked to him and told him he needs to respect your privacy?
He will stop doing this if I go back to him.
You should not go back to someone who is violent like that.
