You sound like you have the same "guilt" I have, I know there was a couple of years I was the WAS, and then it seemed when I woke up and realize I wanted this man this M, then BAM He hit me with BD.
I forgave myself, and you will need to also if you have not. It sounds like you have a plan in place, try to sit still in your feelings and thoughts.
Believe me I know its hard! Your feelings are back and forth on if you want your M or not, like mine. Until we are 100% sure we are done we must be careful.
