Hi Dr Laura.
I believe too many people are looking for or getting into a relationship for too many wrong reasons. Some want to be "happy", some are afraid to be on their own, some think it gives them more meaning to their life, and some just "want" it. Most people look for "eye candy" and don't care what qualities that person possesses. Or the first person who shows them any attention, they attach themselves to only to realize they aren't the person they wish they were. They then find themselves wanting out or wanting more. This is the point at which children get hurt and lives are ruined.
So to sum it all up, common reasons for breakups are people not appreciating who someone else is or isn't. I learned in my 52 years of life is that we need to love our spouses for who they are, but also for who they are not! Just my two cents!
I love your program. It has formed me and made me the man I am today! Keep talking, preaching, and nagging! No words could ever thank you enough. And... you make me laugh!
