Have you talked with your doctor to see if there is an issue with hormones or something else ?
Just to rule out the chemical aspects of desire.
Personally I could not even handle an accidental brush from her hand back in the bomb and recovery stages. It was one of my reasons for moving on separately. As it is a very important part of a relationship.
But for you I think it is more about the fact that your H is not truthful to you and has not been for years. And you are not sure if it just you that has had zero sex the past year. So no trust. No being vulnerable. I would just assume that it has been PA back in 2006 and the past few years as well. As he had it set up to go away for a few days a week. At his age to not have sex in a year is not normal , unless he is a narcissist or has a physical issue. Is he still away all the time ?
I am sure all this is floating around in the back of your head. You have worked very hard at saving your marriage for six years now. That is something to be extremely proud of. But perhaps sometimes you cannot fix what is broken. And it seems that truth and trust have left your marriage which are two of the foundations for desire and intimacy.
