Mojo,
I know what you are feeling. A profound sense of being ripped off, among other things.

Just allow yourself to melt into this bitterness and see where it takes you. You may come out on the other side with a firm resolve to see this thing through and grateful to your husband for his honesty.
You may not.

I would hope that he is willing to work on his other emotional issues, in light of the fact that his libido is what it is. You can't be expected to live your life with all of your major needs going unmet.

I also have a feeling that, soon, a sense of relief will wash over you as you realize what your husband is made of and what that means to you. I know that I was holding out a lot of hope that H would morph into a horny guy and I basically tortured myself with this notion. Having it thoroughly debunked was both a major bummer and a relief.
It is also a large part of why I am still at it, years later. I suppose I am still coming to terms with this fact:
Here you have a guy who, when he wants to, displays sexual aggression and horniness to rival the best of them. So it is a bit of a mind trip for me because I see that he has it in him, he just won't let that guy out of his cage very often. Or that guy doesn't want to come out very often, is more the case! At any rate, I am still on the road to acceptance and that is why I am still here.

I wish you well...I know this mind trip will occupy you for a while and then you will be back, General Style, with your plan of action.
