I have began to read your post and had to reply to his one. My situation is the same but the opposite. I had the PA in my R. It would come from both sides. The thing that lead to the D was on my hand. He decided he had enough and walked away. It hurts because all of the time I hung in there with him, but the few times that and last time it was on my hand he leaves. Doesn't want to work. I kid you not, everything that I have read so far is in line with my H. He is doing the same things as your W and my feelings are the EXACT same as yours. The waves, the hurt, the moving forward but waves of feeling unsure and lost. I'm in a lost "moment" now. It hurts so much.
