Some women only feel good about themselves when they are part of a couple. Super codependence. Some women define their identity through a man. It is a gender thing that fortunately is being evolved out socially. The most important thing for them is to be in a marriage. That is the only way they can accept themselves. They are very afraid to be alone ultimately.
To be single (like myself) there is A LOT of self confidence I must have to get along in the world...and I am even in a relationship right now. Single women are about as welcome as lepers in most social situations where I live in the south. Most women cannot handle that.
