I think it's great that you care enough about your husband and your relationship to read the SSM and seek advice on this message board. I'm in your husband's situation as opposed to yours, but it's nice to see a post from the low-desire partner in a relationship (especially a female) because it helps me to understand better what might be going on in my wife's mind. My relationship is similar to yours in that I'm the one to commonly share my feelings while my wife very seldom opens up. However, unlike you, my wife doesn't like me to share my feelings because she sees the fact that I'm unhappy as a criticism of herself. As a result, I'm trying to learn how to communicate with her without coming across as critical.
Like you, my wife has told me that not feeling close to me has a lot to do with our lack of physical intimacy. This surprised me because aside from our "monthly" argument about sex we get along very well. I feel like the reason she doesn't feel close to me is because we've gone so long without sex, kissing, cuddling, etc., but obviously she sees the exact opposite. I apologize that I don't really have any advice to offer at the moment, but I will follow your future posts and offer some insight whenever I can. If you have an opportunity to read through my post, I'd be interested in any insight that you could give me as well. Good luck finding some answers to you problems.
