Today’s women are extremely picky about what they want in a partner. They search for the perfect man, who does not exist, and they set their expectations to an outlandish level. Ladies, there is no perfect man, nor is there a perfect woman. Relationships take work and need compromise from both parties in order to succeed. Sometimes, relationships fail. If you are 40+ and have never been married, more times than not, it is your own doing. I know women who are extremely high maintenance, and men are just not always attracted to that. No one wants to be with a ball and chain or a needy/clingy indecisive partner.
Young women are picky about partners; 40 year-old women are desperate for a child instead - they can’t be picky anymore.
