Marriage is something that you have to want. It's very difficult, but rewarding. It takes work to have a successful marriage. Many marriages fail because people expect it to be easy. The best thing to work on in a marriage is how you fight with each other. Once you learn how to fight productively, you will decrease the likelihood of there being resentment and contempt. Those are the marriage killers. Look at your relationship like a bank. If you withdrawal (actions that cause hurt) more than you deposit, the account will run dry.
