I wouldn't behave like that.
well, that's the problem.
You behave differently, and you've seen in the past how that can end. It really is up to you to decide if you want to behave in a way that attracts this guy.
Having seen your more recent posts I'm inclined to go along with B00: he's got a friend, he's got a lover, and he's got work. It sounds as if it would take a lot to persuade him to change course, and given that you're (understandably) reluctant to become a different person in order to make it happen - I think you'd better resign yourself to it staying the same.
If you really do want things to change, you already know how. But I think you're sort of hoping HE will change; and I don't think he will.
