Muddle, just my 2 cents here, but your W is one confused lady. She is angry at herself and seems to be taking it out on you. She does see your changes, believe me, that is probably what is making her even madder. The fact that you are fighting for your M. She probably doesn't feel like she deserves you. She probably feels worthless and unworthy of your unconditional love. What is it that DR says? Don't believe everything they say and only 50% of what they do, something like that...... She is in a lot of inner turmoil that only she can figure out.
Again, just my 2 cents. Hang in there. I may not always post, for lack of advice, but I do keep up with you so you know you are not alone.
