My husband and I will be married 40 years tomorrow. I still remember, very clearly, walking down the aisle and thinking.....what am I doing here?? this is forever!!!... I was 18 and my husband was 24. It never occurred to me that I could just divorce him if times got tough. I was in it for the long haul. I was very lucky. He is the best thing that ever happened to me and I thank my lucky stars every day. I don't have any advice for you. I think it is perseverance and a lot of luck maybe.
