I just don't know what are the changes that I need to do or what he needs from other than the obvious (changes in me and how I react or not react to his temper). H will not open up to me whatsoever. He only recently started to tell me how good he's been doing at work.
I gather your H has told yuo what he needs from you. That is great. I thinkk this is how the OW has an advantage over me b/c she hears all of his complaints and then makes sure she doesn't do them. I know that he seems a lot calmer since I avoid arguments or try my best to ignore it when he pushes my buttons.
