Welcome to PC, Bookish.
I don't really know what to say. I mean, I imagine it would be frustrating to have to keep someone else's feelings in consideration when they have (possibly?) hurt you by leaving. You haven't mentioned how you feel in all of this. Do you really want him in your life? How are you processing your own feelings? I suppose taking these things into account would form a part of how you react to the situation. Everyone is different. But in my opinion, since he's the one who bailed, I would leave it up to him to make the next move. After all, in my opinion, you don't really 'owe' him anything; he's the one who left. (Not meant as a judgement, simply an observation.)
I see that this was posted a month ago. What's been happening since then? Have you reached some kind of resolution?
