I haven't read your threads sporadically, so this may be something you've addressed already, but can you elaborate on why you say your relationship is an affectionless roommate R?
You mentioned you sleep in the same bed, she undresses in front of you, you get four kisses a day, and she doesn't pull away if you initiate physical contact.
That doesn't match any roommate situation I've lived in.
Also, you say she will do non-date things with you. Can you clarify?
My H and I went to dinner and a play last night. Is that the sort of thing your wife does wih you?
If the main issue is that your relationship is devoid of sex, then I recommend Michelle's book. (Although I was reading it as the low-libido spouse, so it might not be as helpful for you as it was for me.)
You might also try reading other books. There was one written to low-libido women that I felt had the most insight into how I felt and some of the things that were getting in the way of my desire. I wanted to share it with my H and say, "Look at these passages I highlighted. This is me!" I didn't, but I wanted to.
