Something which has occurred to me and I don’t recall this question being asked of you, but do you have strong carnal desires towards your W, I mean do you ever think “Tonight she’s looking hot and I wouldn’t mind........” (sorry I could think of another way of asking the question).
It seems the potential is there for physical intimacy, but all the potential will amount to nothing if don’t have the burning desire, or drive to do anything about it.
I was prompted into that question as you said you were waiting for a sign from your wife, would like to expand a little more on what sort of sign you are looking for ?
