I read your other thread last night. I'm sorry for what you're going through. I believe that my h also had a type of "early" mid life crisis thing. He had a total personality change. Nothing was good, nothing made him happy, work was horrible, life was horrible. Nevermind that you have 2 great kids, a wife, a roof over your head and food on the table. It was awful. I totally understand you feeling like it's not real and he will wake up to see what he's doing. I thought mine would too. He continued to make poor decisions, lie to me about stuff, and went so far as to try to buy a buisness behind my back. He lost his freaking mind. Then he would threaten to leave when he got mad. Well, I finally told him we needed to separate and so now it is all my fault. When men are in that state of mind, nothing will make them happy. You cannot make him happy. Just try to focus on yourself and make your life the best it can be. Thank goodness you guys don't have any kids, because they really lose in all of this. Best of luck.
