She is always good at shuting of, not talking about things. Blaming me for everything. Threatening to leave. Leaving then wanting to come back. The more Im nice to her the worse it gets. I do love her, but this is crazy.
She is probably seeing your attempts to influence her as controlling. Even being overly nice can be seen as this at times.
Pull back and just concentrate on your own stuff. You can't control what she does, only what you do and how you allow it to affect you.
Simplistic statement I know, but keep posting here and you will come to understand the complexities involved.
A minefield is a peaceful place as long as we dont go wandering about all over it.
