The GALing is (Getting A Life) exactly what you've been doing w/ your friends. Dim is also what you've been doing- not kissing her butt, letting her deal w/ her own consequences, not calling, texting, pursuing.
Like P17 said- you are getting better results b/c of this- she is being nicer.
I think you should keep doing what you are doing. If you have not set the boundary of not having an "open marriage" or "sharing your wife", I would establish that.
