I am glad that you got to have this conversation with B. I know from my own very recent experience how being able to tell one's spouse (feels a little odd for me to refer to mine that way, but for the sake of ease of writing, there you have it)what one's current feelings and state of mind are is invaluable.
I think I have posted on my thread that I was advised to write a letter of release to Z and I did so a while back. For the longest time, I thought of it as releasing him. But after reading your words, it occurs to me that we are also releasing ourselves when we release them.
Since so much of this work really needs to be about ourselves first and apart from our spouses, I think it is very important to release oneself.
Be kind to yourself in the days to come. This sort of endeavor can trigger lots of different emotions. Not saying anything negative will necessarily happen, just be open to feeling whatever arises in you. I know that you will do this; it is clear you have been doing so all along.
