Actually, looking over the posts on this board, there are quite a few marriages going without - I don't know of very many that are as long as my drought, but there are a few.
I can't say for sure what she thinks the vows meant - I would certainly think "love, honor & cherish" would cover sex, but that's my opinion.
To answer your last questions - yes, and yes. She has no interest at all in sex. She says her libido is gone, and at 41, she doesn't think it will return. Additionally, we've had some relationship problems (see my other post - Not a Good Start) which definitely contribute to her lack of desire. Factor in some health issues, and that's where we are now.
Besides not ML, does anyone else notice the negative impacts of a SSM? Do you notice yourself being short-tempered, resentful, and distant? Just wondering if I'm encountering "typical" emotional fall-out.
