This is what transpired.
SIL, did not yell at W. She helped facilitate D11 in saying she did not like the keeping secrets from dad. W shared that she had a phone call with a L, and will most likely have a consult this week. We then talked about hoe the M was dead, and no going back, that D was inevitable. She lead this conversation. SIL, was still there, and sort of served as a mediator as we talked about physically separating finances, custody, and other stuff. We then also sat S7 down to retell him what was going on. I'm afraid we broke his little heart.
We all cried.
At the end, W said she felt like she wanted to hug me, but did not as it would be weird. She also said we couldn't go back to save the M, as I'd never be able to trust her again, and that too much has already be done (defriending my family). I told her that not as a plea, but rather facts, that my family and friends do not know the full truth, and that I beleivr anything can be fixed.
S7 and I left to run to the store, and pick up dinner.
No clue where I am at. When if she will file.
