Why Do Women Feel as Though We Have to Have a Man in Our Lives?

From the time we are old enough to play with baby dolls, our nurturing sides come out and society dictates that to have a baby, we must have a daddy. Could that be the reason most women feel as though we are not complete unless we are in a serious relationship or married? Is that also why we stay with a man that either mentally or physically abuses his wife or girlfriend? Because she feels she HAS to have a man in her life and is afraid if she leaves him, she will not find anyone else and will be single again? Or could it be that if she does find herself single again, she will be back on the "dating scene" and will have to dress up and put on makeup, etc. How many of you ladies are comfortable in your own skin; leaving the house without makeup and all "dolled up?"
