Marriage is such a complex relationship. And the relationship between the partners is always different. In some ways I can relate. My husband is a loner and kind of cold, not a talker. Other than pecks hello and goodbye, we don't kiss much. But he has a good appetite for sex and keeps me satisfied there. So the rest of it, I don't care about.
There is a sex-starved marriage board on this website. Maybe some of the people there could give you advice on keeping love alive with a low-desire (LD) husband.
You are doing the right things in keeping the focus on your marriage and cutting other men out. Retrouvaille will teach you tools to get closer with your husband, and draw out his emotions. It will be hard until you get there. Just keep working on building your house. You cannot build it up with a crowbar or a wrecking ball. So just keep at it by slowly building, one nail at a time.
