I don't think, if they broke it off, that I'd talk about their having hurt me or their behavior at all; presumably they broke it off because there was something with me that they had trouble with (not that it was my "fault" or my "problem"; their reasons for their actions are their own and not mine). But I wouldn't pay much attention to any hurt that had come my way if I wanted to restart the relationship, other than wondering why I wanted this relationship if it had hurt me. I think my talking about their behavior at all wouldn't help or be appropriate since I can't know what's up with them unless they tell me. But if I truly wanted to start again, I'd start fresh and just call and ask them how they are and see what happens from there.
