I suspect these LKB are too shy to ask for what they want. They always wanted to have this notion of being on top of situation and they claim they are better educated and more composed.
In the end, they lose the skill and ability to openly communicate to what they wanted from their spouses or partner. The more they hold on or can't open up, the more they find themselves in the more awkward situation. As times goes by, they become less healthier and also lose their ability to communicate and attract partners.
The spiral goes on and on
