WAW and 4 kids

"my alternative is to say "I don't want to talk about it" I guess. Should I do her that favor?"

I wouldn't. I would tell them your side of the story and then suggest to them that they talk to your W directly. Tell them you have nothing to hide and are willing to talk to confirm/refute what they hear from her.

You should also tell them that your W doesn't like you talking to her relatives so you are concerned about the blowback you'll get from her. They should understand that.
