Honestly,
I had to go back to my post b/c from reading your reply I assumed that you caught me on one of my bad days.
Reading it, I think that you did not. Actually, it was a good day, and I just my thoughts were more profound than I could articulate.
I am sorry that you feel that you do not love your wife.
I am not in a position ot give you advise.
I realize that the A is not your fault, as with my H, there is something sacred which was violated, which I never dreamed could happen. For me, I have decided that I can love my H beyond the A.
What I meant by the underlying reason, is not that you did something wrong, it is that your W preceived something lacking which she fould fulfilled with OM, that is the thing that needs fixed.
I am sorry for your anger, there needs to be a time to forgive and get passed the anger, you have to decide how to get there.
