I may be an insight into your wife. I was the one who had the affair in my relationship. What your wife is doing and how she is acting screams affair or that she is about to. I started by going out with friends a lot, too. Anything to get out of the house and smiling and having fun. My H made me feel less than special, not to mention that I was depressed. At that point there was nothing my H could do that didn't make me p&ssed off. Does that mean there is nothing you can do? No! Start thinking about those things that she has said to you over and over and over that she needed from you, that perhaps you brushed off as unimportant. Take a hard look at yourself. Be honest. Start doing those things. Also, do what others have suggested. Work on yourself. 180s. Be strong, confident, attractive, happy...someone that ANYONE would want to be around.
