Well, finally! It's about time she owned up to her behavior (at least to some extent)! She must be having some amount of self realization that she's pushed you and her attitude to the breaking point. I'm sure you're skeptical and deservedly so. I'd say call her out on following through with counseling. Hopefully the counselor will help you to see if this simply damage control and if she intends to slip back into her old behavior. Time will tell and it'll take time to heal the scars of resentment. I always like to say, "Hope is not a strategy, but it's still good to have, especially if you don't have a strategy!"
