"I have little desire to try 4-5 times in 7 days she has expressed how she is completly uninterested in this M"
Then stop "trying" and just start doing. Treat her as you would a friend. The resentment will well up in you, but stuff that down as best you can. The way I got through that period was I saw my W as one of those crazy homeless people that you see sometimes muttering to themselves. After that, nothing she did or said really bothered me. I just tsked tsked it and chose to be happy.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
