When two girls like the same guy?

Anonymous
My guy friend and I have been close for around one year and everyone around us teases us about dating each other. This guy is quite good-looking and has a great personality; even one girl who has been in a relationship for two years said she liked him and that he was cute.

This semester, this guy and one of my best girl friends have been taking a class together. He's pretty clueless when it comes to dealing with girls, and likes to make plans to study together, so the two of them have been seeing each other a lot for study sessions, and my girl friend most probably likes him. She asked him to study with her and didn't want to tell my other friends and I where they studied so we couldn't join them.

I'm sure this guy likes me (according to some questions I have asked on here), but I would still like to know:

1. What can I do to make sure he is "immune" to my girl friend's "advances"?
2. What can I do to win his heart back and let him know I am interested?
