5. The man tries to isolate you from your friends
Abusers are selfish people. Most of them won’t allow their partner to meet other people. Your friends whom you love and respect can become a real problem between you and your partner if your guy is an abuser. He will tell you negative things about your buddies trying to isolate you from the rest. This is not really normal and typical only of abusers. Do not let him manipulate you.
