Have you ever gotten married for the wrong reasons or know someone that has?

My guy friend and were talking about marriage and relationships. Anywho, he said that if he just got married and had a family all his problems would be solved. That's all he talks about is getting married. Every female he meets he puts her up on a pedestal then it always blows up in his face. I told him to stop rushing and get to know the person first. He says he kinda jealous that his brother (20 yrs old) who is 6 yrs younger than him is married and has a son. I guess I'm different I like to take relationships SLOW, because want to know who I'm dealing with. If and when I do get married I only want to get married once. My biggest fear is marrying a psycho.
