WAH in MLC with PA

[DiamondGirl]

What should my goals be with regards to interacting with WAH? I'm not sure how to talk with him.. because at some point I'll have to..

I get that I need to validate his feelings but do I call a spade a spade? When he goes off on how everything is my fault (according to SIL he still is) do I point out to him that having to work on custody docs is a result of his choices? Or do I just keep my mouth shut...

This is the area I'm not sure how to proceed on... When he's accusing me of things that I'm not responsible for, or that he's brought on himself, do I stand my ground or not? I don't want to make a misstep here..

Do I put off looking for "small signs" until he comes back to earth (if he ever does)?

Should I accept any requests to meet with him (though I don't think I can not be emotional right now)?

How does dealing with the MLCer differ from the DR process? Does Acting As if only apply once they are human again?

Just needing some clarification on the steps...(Sorry if I'm sounding clueless but I'm trying to wrap my head around the process to cement it in for the "rough days")

Thanks,
