I have had a very interesting marital history that's for sho.
First marriage at the age of 23, total disaster (6 years 6 months), second marriage at the age of 47, loving and faithful wife but also in declining health leading to a nightmare in Maine for the last 8 years of our marriage (11 years, 2 months), current wife that I met on CC at the age of 59, loving and faithful, playful and affectionate, serious and considerate, relatively healthy (3 years, 5 months and counting). A total of over 21 years of various marital experience, some doom and gloom, some heartbreaking and some very happy and content.
I have indeed undergone a tremendous amount of training to reach the point where I am today, a loving and faithful husband to my wife. In fact, I was loving and faithful in all three marriages even though my first wife was horrible and unloving and unfaithful.
My most challenging marriage was my second marriage. I knew she had arthritis and other medical challenges and I would probably outlive her but God asked me one day if this is truly who I wanted till death do we part. He warned me to count the cost because if I said yes there was no going back. This was to be my ministry and something that He had prepared for me accomplish for years I said "I do".
My current wife will be my last wife. I have heard it said to never say never but this will be it for me. One way or another when this marriage ends by the death of either her or me my work will be finished.
