The lack of intimacy, touching and hugging etc is very difficult to deal with. My wife won't even sit on the same couch as me if I am already sitting down. Does she actually do this on purpose? Who knows what is going through her head.

It is really hard to grasp that I have been that bad of a husband that would result in my wife becoming this totally cold and indifferent person.

I had issues with my wife over the years, but I never stopped loving her. She seems to think that she was the perfect wife and I was the most horrible person on the planet to live with.
