I can promise you if you limit contact, keep your boundaries enforced, stop focusing on her and really dive full throttle into work and meeting new friends when you do talk to your W she will seem quite unattractive unless she starts making some changes.
Its funny you mention this because I was just thinking it.
My wife (as usual) was pretty mean to me today when I needed to talk to her about some basic buisinessy type stuff, and after I had a great weekend with new friends, I really didn't care.
She emailed me like 4 hours later to apologize for being that way, and I don't feel the urge to reply that I usually would.
