WHAT DO I DO , IM SO CONFUSED?

Sounds like you only want him cause you now can't have him. He is with someone else - respect that. I have had many a girl try to steal my man and they do come across as being skanks - even if they don't see it. If you TRULY want him to be happy, tell him you wish him well with his g/f and only want to be a supportive friend NOTHING more.
