It depends how you break. This is my opinion. A good friend of mine break up without talking to me. She knew that I'm more then a critical thinker. We spend some holidays together. But there was no letter or anything. So I don't know, if she like's to meet me again. (Looking for words, try to reconnect someday.) Sometimes I think about reconnecting. Sometimes not. If she talk to me a little bit more before, maybe she could get much more help as she thinks. But I feel hurted thrue her.
On the other side I work from inside. Only thing I can do at the moment. I work on a sister to reconnect to her sister, family can't broke. It looks good at the moment. Maybe the final part is to hear from the other side. Sorry, but it think it's to easy to give up. This is one reason to stay in. (And I don't shun my da family.)
