Once again (in this post as well as in your other one) I wonder who you're trying to fool? Us or yourself. It's obvious that if you keep having sex with this man that you will wish you could have a relationship with him. As such, my suggestion is that if you come to find that he's not willing to go out with you, hang with you without having sex, only interested in "dates" that are in places where he knows he will get laid etc, then you best distance yourself now and stop pursuing him or you will soon be gutted. You were very upset with the other guy... what will you be like with this one when he doesn't feel the same way you obviously are feeling? (already).
