I understand what you are saying, and I respect your POV on this. I have a question for you though, it's truly out of curiosity...I have a tendancy to think ahead.
Ok...lets say you can get to a place where you can accept that your R with your W is going to be basically non-sexual (lets assume it happens every blue moon for ya...hey I'm optimistic). What happens if a woman comes along that you find yourself attracted to? It's not unreasonable that this may happen.
You're a strong man, you can probably resist the urge to have an A....but what happens when the resentments pop up again that you won't have the R with your W that you want when temptation rears it's head?
I just have a gut feeling that at some point this is something you will have to deal with. Have you thought about this? If so, what are your thoughts?
Speaking for myself only on this...but for me, I could see potential disaster brewing if I was dead-set on staying in my M. I'm curious to hear your take on it.
