J, think about how your distancing has contributed to his pursuing you before. If you become enthusiastic, I think you're going to experience the same pattern all over again in that he'll become distant.
I think this has been dragging itself on and on in your relationship for a while. You move in closer, he backs off, you back off, he moves in closer. It won't end until one of you snaps. You've got to stop the pattern, and the only once who can change that is you. Right now, you're about to succumb to your pattern again. Resist it. Stay backed off a bit.
