Ouch. I'm sorry. Break ups like that hurt. Whenever its happened to me, I have tried to make contact and be friends and its never really been taken to well. They seem at pains to please me but also I feel bad, needy and kinda pathetic. For me, its never worked out well trying to reconnect when Im still hurting.
I find doing alot of crying really helpful. Avoiding their FB pages and just getting upset and talking about it. Experiencing it and greiving.
