After 37 yrs with the same woman, all I can say is I am one lucky SOB.
No, it hasn't been easy but anything worth anything isn't easy.
First rule of marriage, both your lives are an open book, she knows all and you know all on her, simple...its the golden rule.
From what fellow friends have told me that have been married multiple times and yes, we do make mistakes and sometimes you finally get it right is the grass is not greener on the other side, you still have to water and nurture it to make it grow.
Don't worry be happy, did you know that the longer you are married your net worth goes up expotently besides I don't have a clue on how to wash my clothes or for that matter buy clothes
