Why do men are not satisfied having a single relationship?

Men that feel that they need to go outside of their marriage, for relationships are usually just insecure and need that reurance that they are macho. Women do the same. No it is not right for either to do so. Divorce has become a joke, wedding ceremonies, a bigger joke, if you believe that a divorce is a easy way out. People are just fooling themselves and the only ones benefiting from a couple's demise are the wonderful lawyers. Hope this answered your question somewhat.
