If it makes you feel any better, and it won't, I get the same from my mom and sister. They fully expect me to be in a place where I can just say "good-bye and good luck" to my W. I get that they are mad b/c she is putting their son/brother through pain - but I don't think that they understand the feelings that I ("we" here in general) still maintain for our wives. It's almost as if they think we are breaking up with our college girlfriend or something - when it is much, much more complicated than that. We have a child together, we are/were married.....it's deeper than they can feel for us right now.
Counselor told me that I need to establish boundaries with them on the topic of W asap. Maybe you should consider the same.
