I agree with unchien and ML.

If its legally problematic - validation can come back and bite you in the ass. Validate as much as you can - but keep your boundaries in place and watch your [censored] especially if Ls are involved.

I would also find a way to say that you will be keeping communications the way they are. You dont have to call her anyway - that's something she wants, not you.

My W does not communicate verbally save for a few words per week, even though we are still IHS. Text/email only.

In a way it is good because I can edit what I'm going to say before I send it. I have reduced the clutter of my words, often writing out a whole thing then chopping away at it until its concise, straightforward and businesslike.

I feel for ya, brother. This is a weird place we are all in.
