I solved the feelings about my first breakup by channeling the anger into bettering myself. Perhaps not the healthiest thing to do, use anger like that. But still. By the time I'd finished what I set out to do, the hurt was gone along with any lingering attachments.
Though at least in my case, there was a fairly legitimate cause to the breakup. I was stalled in a dead end job.
As I recall, the schism between the two of you was more ideological and religious, though I haven't been following closely, so that might not be an option.
