Marriage is humbling

The life of being married is a humbling experience. Not many people make it past a certain number of years. Once you think you have the remedy, things sneak up on you and tell you otherwise. We’re dealing with another personality and the ever changing personality of our self. You pray day to day and have faith that god will see you through the changes and bring you out stronger than what you were when you went in. Is this God plan to have divorces or wanting to be with someone else because your current situation isn’t going as planned? I don’t have all the answers, if anyone out there does, please help me understand.
