Have you thought about writing her a letter, conveying the depth of hurt you have been going through, how you feel about all of it, how you see it? And, what you have to do about it now (stop the game, or whatever).
You could give it to her now, or when she is expecting you to perform.
You write well. And, you probably can anticipate her complaints/on-the-fly rebutle. But, if it's all on paper, and you're not around when she reads it, maybe she'll give some of it time to sink in. Besides, it sounds like face-to-face communication doesn't work well for you two.
Don't take my word for it, though. Just a thought.
Also, is she otherwise happy/"normal".
And, again, I know this probably doesn't help. But, I can really sympathize with the need for the blue pill. Honestly, before I ever read your thread, I've thought there may come a day soon when there may be too much resentment involved to successfully accept her begrudgingly given time in the sack. There have been some close calls.
Also, Cemar recommended to me a book called "The Way of the Superior Man". I've had it for a day and read a few bits and pieces, and I think it has something to say that I need to hear, especially about how she percieves me as a sexual being, and how maybe I live my life too much at her whim. You might check it out: http://www.amazon.com/Way-Superior-Man-S...78229521&sr=1-1
It's an unusual book, and seems to be just one man's opinion, but there also seems to be some wisdom to be gleaned....taking what I need and will leave the rest
