Given all the baggage from her adoption, and the fact that she is very cordial, if not outright friendly towards me at times, I think we are dealing primarily with mental illness/MLC. That's not to say there isn't a WW/OM component here. This morning, for example, she texted when she'd be home for Sunday dinner. She indicated she had to leave earlier than usual after dinner, and I told her I had plans to go out tonight. She then texted that she would rearrange her schedule to accommodate my plans. Then she started joking about things I forgot to get for sunday dinner (we are having tacos lol), including texting "lol" etc. She also likes anything I post on social media. I find these things odd if I'm truly the bane of her existence.

Sandi, I think you nailed it in your most recent reply. She is burnt out and needs an escape for at least some temporary relief while she tries to sort herself out. I'm really focused on following Sandi's rules. I've done a pretty good job, despite an initial bobble immediately following BD. Will she ever self-realize her unhappiness is an inside job, and blowing up her family won't fix that?
