Keep your chin up, you are actually doing fine so far. Confusion and indecision on her part are ok, it's a natural stage she needs to go through before believing things can be different. If she is determined to leave and she is no longer expressing confusion, you are in more trouble.
You must keep yourself together. I keep suggesting things to work on YOU, but so far you haven't mentioned anything that is just for you. This is very important as you need to do this in order to stay focused and keep your emotions in check. I still recommend those books as a place to start.
I have no advice for counseling sorry, I do not know what would be best and I have never been in counseling. Perhaps getting her to explain what she is most angry about and validating it would help? Not sure, coz it might just open old wounds too.
