Marriages don't work out for a lot of reasons. Expectations and needs are two major reasons. People have strange expectations of marriage. They think your feelings will never change and love is automatic and that you should not have to work at a relationship. If you go into a marriage with those beliefs, then we will see you in divorce court.
Marriage is a lot of work.
For most of our time on Earth, we needed to be married to survive. Now people can have a long independent life full of fun, based upon their own money, so the economic need for marriage has decreased. We are left with the emotional aspect and that is easier to walk away from. However, man has an inherent need to pair bond, so marriage is not going to disappear, but we need to come up with a better understanding of what makes it work. Thank you, Mr. Freeny, for all of the great advice on love, sex, and relationships.
