Cobra What you can do is ratchet down your expectations, put out of your mind any desire for a better M, better sex, better anything. Instead focus on the here and now and forget that you ever tasted of the forbidden fruit. Yeah, that can make you feel better, until you remember how things used to be.
Cobra, how things used to be isn't likely going to happen again.
I do see the above post of yours as what is happening with me. I also see more parallel activities going on between BB and myself.
I will say NMMNG and a few things on the forum have gotten me to expect less and be in charge of me, my feelings, and some changes will cause me to appear less dependent on BB or the M.
I am sure parts of the concepts will work. I don't know if it will rekindle my desire for the R or BB, or rekindle BB's desire.
I mostly only have me and that is all I can change.
And, yes you can eliminate some frustrations by giving up expectations. I see a place, not necessarily happy like you originally wanted to be, but better in some ways.
