WTD, I totally relate to your story! My husband's the same way. Christmas was fine, we talked about next year's Christmas and everything (actually H did the talking). Then suddenly he started acting strange, and then on February 7 he accidentally sent me a text meant for OW, and a week later he moved out. Have no idea where he is staying. We have a S4, whom he loves and comes to see. He's like someone I have never known. I'm doing fairly well DBing, but I don't know how long I can take it. I am not from the US, and my plan is to move back to Europe w S in December if he hasn't come out of it then. My H suffers from depression (untreated because of lack of insurance), hates his job, feels miserable about not having a good career, no $$ and so forth. It's very difficult. Hang in there. At least you are not alone.
