why can't your partner treat his girl friend special when he goes out
Very bad !. It's time for a heart-2-heart talk. Tell him that as his girlfriend you are supposed to get a special treatment. Please note that any good relation is based on 4 pillars: Trust + Openess + Communicatins + Respect. By raising that point you show that you trust him, you are open to him and you communicate with him..... So in a way you are contributing to create good relations (and show him the way).
