Most Helpful Guy
You're not even in a relationship with the guy and you're already this insecure. It'd be best to just leave him alone.

Welcome to the "I like the player kind" world.
I can't help it, I always fall for the player XD
Are they friends, or friends with benefits?
If he's good looking he might have a "more than friendship" relationship with those girls.
My advice: Just don't fall in love because you could get hurt. Try if you like him, all players fall some time, but don't fall in love...
