I have the same feelings and thoughts you are having. Like you, a few months ago I would have jumped right back into a R and hope that everything would return to normal...WRONG!
My H also updates me when OW contacts him. I thank him for letting me know; however, I do and I don't want to know because when I do know it makes me mad that this b!tch can not let go and let H and I work on our M.
In the beginning when I started DBing, I didn't think it would actually work, but it does. I'm so much a different person than I was 8 months ago. The most important thing I have learned is patience. Like you, I'm not ready to move over to the piercing thread.
I think you are doing an outstanding job. Like you said, take each day one at a time. I'm sure your H is adjusting to being with you again and there will be awkward moments, don't let this discourage you.
