whatdidido, thanks so much for you post. You have such great insight and your relationship with your H is an inspiration to many of us on this site. I do understand that a couple can make a M work if they both are willing to make that choice. W has not indicated that she wants to make that choice.
I now have had time to think about this R. Here is what I feel.
The first...I will not be her second choice or be her back up plan. If she decides that either OM or her new life is not what she wants then she will need to continue without me. I don't see how she can convince me differently. Does anyone here want to volunteer to be a back up plan?
Second...even if she decides to work on the M, I am not willing to go back to what we had. Right now she is not capable of being a good partner in a R and I don't think she can change.
It occurred to me that she is taking over the MC sessions to work on herself and not on our relationship. You can argue that she needs to work on herself. I agree.
