Then don't. Talk to her as if she were your acquaintance and not your W.
"How do you handle friends bad mouthing your W."
First off you control what you tell them. You're looking for support, I get that, but does it really help you and your daughter to know that your friends think your W is a dirty wh@re?

If you hear your friends saying something negative about your W, turn to them with conviction and tell them that you would appreciate it if they would stop talking about your W that way.
