To give you all some encouragement, I have been married for 14 years, together off and on for 20. She wanted a divorce and wanted to move out the first of January. It took a very short time for me to realize how dbing was affecting her. To take a line from this thread, I am a man, I see what works and then I repeat it over and over. I stopped all realationship talks, I acted as if I had a life on the outside, when we spoke on the phone, I usually ended it after a few minutes by telling her I had to do something.
Today, we are making love 2 or 3 times a week, hugging and laughing again, telling me that she has enjoyed the last few weeks with me, more than the last 5 years.
I tell you this not to brag, but to tell you that it can be done, too much gloom and doom on this board. My situation was easier than yours, my wife did not move out, but your wife sounds like she is generally interested in you and your life. That is something my wife did not have in the early going, she had totally quit. Like I said, wanted a divorce today!
Good luck and I hope this gives you some encouragement!
