AH, I have a sitch which is similar, but with kids, H moved out and immediately started up with another woman
But the reason I am writing is I really think we are in the same geographical area :P and wanted to wish you a Merry Christmas.
It seems as if you have resolved the R. What if, all of a sudden, let's say, H really wanted you back and started up DB'ing etc. would that change your mind at all, or too much water under the bridge?
