She should be working on her issues but should also see there is damage and pain on my part to address, as the book details. Each passing day where she thinks only of herself is hurtful.
The problem is that you seem to think that she is trying to reconcile with you. So far, nothing I have seen is suggesting that. She may be sad, guilty, heck, maybe even remorseful. But I havent seen her come out and say she wants to get back together to work on your relationship.
So, I dont understand why you are reading books about piecing. Of course you are going to get sad. How about instead, you go out and do some kind of GAL. Go make a new friend. Go try a new activity. Even if she shows up and you both heal, what will be different about you this time in order to 'make it work'?
You have to work on cleaning up your side of the street. Stop worrying about the trash on her side for now.
