I have spoken to many older individuals who left their 1st marriage and reflect back with regret after 20+ years, "She didn't get the best of me when I was that young. Today I am settled and a much better man." "My pride got in the way of my marriage. Today, I am older and wiser." "She was a good woman to me. I could have been better to her." "I was too young.
