Saving your marriage on your own is not an easy task because normally you would probably think of saving a marriage as being a two person effort. But one partner in the marriage can do a lot to save the marriage. Start by taking an interest in all the day to day events that lead to deeping difficulties. One person can not fight with themselves. Your partner can not become offended if you are careful about your actions. Forgiveness can be launched by one person being willing to admit their faults and ask forgiveness. New directions for the marriage can be started by one partner. The key question is how much do you want to save your marriage alone and how much are you willing to humble yourself to save it.
