Interesting. I got married in 1980. It's a long story, but to cut it short, I thought a happy marriage and children wouldn't happen for me and I was all set to make my life happy as a single lady. Then along came DH. It took him a while to convince me to marry him, which I did because I wanted him in my life and thought him worth the risk! We had to marry as he was a policeman and you couldn't 'live in sin' in those days. He had to get permission to marry me from the chief constable! Yep, police checks and all that! Also my parents are religious, but the wedding was taken out of my hands. Not the best day of my life, until we went off alone in the evening.
Would I have got married today? Possibly not. I appreciate the commitment DH made to me. Somehow it made me feel more secure, which is daft considering how many couples get divorced.
My son had to get married just to be able to stay with his girlfriend, as she is American. He was not ready for such a commitment, but it was that or being parted. But he says he is glad he has and doesn't have to make that decision.
My daughter has been with her partner for 15 years. She can't see the point of getting married, having been bridesmaid to 3 friends who have all divorced since. She's very happy with her partner. They are committed to each other and have a child.
I know so many people who have got divorced. My DD once said to me that she and her brother were in a small minority. Not only were her parents still married, but were happily so.
I think why our relationship works, apart from the fact we love, respect and trust each other, is that we are not together to complete each other. We are survivors on our own, but life is better together. I can't imagine having a relationship, let alone marrying anyone else.
