I won't inquire about what went on in your relationship since it's not my place, but it does sound like he is just playing games with you. Are you a "good girl?" If you are, which it sounds like, perhaps you keep getting drawn to him because you think he is a "bad boy." As long as you are waiting on him, this "hangin on the line" thing will go on as long as he wants it to. How he has treated you overall up until now is something to think about as well. Only you can make your own decisions. You'll figure it out.
Oh, and you didn't answer my other question yet...
Who is this?
