"I would understand it if he wanted to cheat on his gf with me but he doesn't because he loves her not me." Chances are, if he really loved her and didn't want to cheat, he would have kept his fantasies a secret from you. It sounds like what he really wants to do is cheat without the guilt, or have you not think less of him for wanting to cheat. Sorry. It doesn't work that way. If he truly loves his gf, he will keep it zipped (both his mouth and his fly) around you (and every other attractive woman he may know.) Sounds to me like he's just fishing for your reaction. Be careful not to take the bait.
