Some things that came to mind:

I guess in a round about way, I try to figure out WHY he has so much contact with me. I mean, in my own experience, when I've broken up with someone - I didn't call them, text them, sleep with them. Especially if started another R with someone new. When it's over - it's over. So when SO is doing this I translate it to mean "he still cares" and because he still cares, there's still "a chance".

Is he scared he's making a mistake? Absolutely. Even by his own admission. And as evidenced when I tell him to leave me alone.

Is he manipulating me to remain on the back burner until he's "sure" of what it is he wants? It certainly feels that way.

I'm not making any sense. He tells me he wants to break it off. I say OK. Leave me alone. TELLING him to leave me alone seems to incite him further - makes him contact me even MORE. He doesn't just let me be. My going dark scares him. He's not sure he wants me, but he won't let me go, either.

Everything just seems so backwards from others here on the board. In some ways, I want him to stop bothering me - just leave me alone already. If only for him to go figure out what he truly wants - whether it's to be with me or to be with someone else. He doesn't seem to get that. And I don't know what to do.
