I find it interesting that she is pissed that you moved to the guest room. Either she is having second thoughts about where this is heading or she wanted more distance. In any case, you are giving her more space and she should appreciate that.
Good luck with the counseling today, that may be a bit of a challenge. This one sounds like a tough nut to crack, possibly tougher than my W.
You may want to consider heading to your mom's place for a week and going dark. Give her a dose of reality.
