You are weird for having an issue with him having a lot of girl friend.

One of my girlfriend's best friends got in a relationship some time ago and all of a sudden he stopped seeing his best friends. Turns out his girlfriend didn't let him meet his girl friends. She threatened to destroy his belongings. Now this guy is the sweetest and most kind man I have ever met. He doesn't deserve this.

I kinda hope you are his girlfriend so that I can tell you to get out of his life and leave him. He deserves someone who loves him. Not someone who makes a wonderful human being loose faith in himself. So if it is you, sincerely from the bottom of my heart. Fuck off!
