I am sorry to hear your pain. I think it has been a matter of timing for both of you and right now it is off again. He knows you are out there and wanting to be with him but he is with someone else now and even if it is a bad relationship, that is where he is right now. If he is ignoring you as you reach out then that indicates that he does not want to come back at this time. He knows you are out there...give it some time and space and let it play out.
