rarechild, thanks. I very much appretiate you sharing your story... it does help, especially coming from another perspective.
My wife just isn't ready to see me with another woman, even if it's her girlfriend/my good friend. She didn't rule it out in the future but I am afraid that my chance may have come & gone... or will come & go... make sense? just don't know. Although it has been a great experience for me, I have had difficult days emotionally & have found it hard to hide. ...working on it.
I am planning a two+ day motorbike trip to get away & clear my head. I think it will do me wonders to get away from the situation & be able to reflect on it without distractions..
And, I will take your advice & continue to treat them well as I have been all along.
