So a flatmate at University I live with is a close friend.

We party often together (sometimes as a group, sometimes us two only) at Uni clubs

and we don't really look alike.

He's a good talker and fun once you meet him (also is fine with chatting up girls), however his appearance

is mediocre; doesn't lift, doesn't dress well and looks like a nerd in general. He's also not proactive in clubs, mostly follows me around.

I've given him some pointers on that from what I've learned on TRP (however its gonna take time to implement).

How can I make the most out of the situation? make sure he doesn't sabotage my efforts in clubs etc.
