Heyya SD... Lotsa good stuff here. I agree w/ Jeff and the others that an EA is just as bad as a PA and I think in some ways it is worse b/c it is a violation of our secrets/hopes/dreams in that people in EA's share so much information with the OP.
So... just wanted to say I'm glad you're setting boundaries. I hope your H can really get how toxic having LW in your lives is for your R. You deserve to be heard.
