I'm working on ways to distract myself. Lately I've been binge-watching Only Murders in the Building, gaming, and reading. I'm also working how to respond when she is obviously trying to push my buttons. - it really doesn't seem to make much sense to confront her - she just denies and/or claims she can't remember.
I would like to continue to find ways to make her uncomfortable when she is obviously playing mind games on me.
