Yes, MKB, get your mind off things, and decide on an hour of the day to think about your next steps. If you decide to end your M, you will be afraid, and for what I've heard, the person who initiated D always wonders if he did the right thing. This is one of the reasons I told my H he had to be the one to file, even when I felt I could not recover from the A. If you decide to continue waiting and trying to fix things, you will still be afraid of making the wrong decision. I know it's tough. Your will feel one way one day and a different way on another day. This is why it's so important to give yourself plenty of time.

What was your H's attitude when he told you about his new A? Was he embarrased/regretful or did he seem to not care? Did he say he was sorry? What is his attitude now?
