I have the same thing, BT. My W said she has lost the feelings of desire for me as well. And I believed her, because sex for the month preceding the bomb was almost non-existent. But now I am not so sure. Last weekend we were cuddling on the couch at her temporary apt, and we started to get physical. She said, boy, you sure know how to push my buttons, and it was actually ME that put on the brakes. Glad I did, too...six weeks of celibacy is no fun!
Anyway, my point is, she may need to get something out of her system, or she may have convinced herself of her position, but this may change after she has the freedom to do as she pleases with no pressure, neediness or guilt from you. You standing in her way and making her feel guilty will just strengthen her resolve.
This will be the hardest thing you ever do, but it sounds like you need to step aside and man up, buddy. What you are doing is clearly NOT working.
