Quoting luvhubby: We all want to be desirable to our spouses the way we desire them and when the LD partners are not even interested in being interested, unwilling to even try, then worse still, the LD partners feel unloved, uncherished and that leads to other marital problems like an A for example.
You just made me realize something! I think this is part of the root of my H's unhappiness that led to A!
