Women LOVE to bitch, piss, and moan. What they don't like to do is act to make it such that what is causing them to b/p/m is no longer an issue. I think the best course of action is to not allow your woman to turn you into a complaint sponge. Working the situation such that she uses her girlfriends as complaint tampons is certainly the way to go.

I would love to hear your mechanisms for telling your woman to take her bitching elsewhere.
