I'll just echo JRs comments that you appear to have handled it extremely well CA. I've been through similar w/ my WW and haven't handled it remotely as well as you did. I was also shocked by just how much spew came out of her and how much she seemed to enjoy taking shots at me during it. There were times that I looked at her and I'd swear she had a smile on her face. Frightening.
That's great that you've got a consultation w/ a L. I agree w/ AP (as he's the one who pushed me to setup my own) that you need to know your options. Be prepared for your WW to try to misinform you around custody/financial support if she thinks you haven't consulted an L.
Some vets can give better feedback, but I'd offer you stay the course here. Laying some good groundwork for the future. just make sure that whatever you say, you are able/willing to back up.
