I think everyone is different, and know when they wish to get married.
My mother was married at 16, and 9 months later I popped out. Mum and Dad were married for 51 years (Dad passed away in 2000), and life was always good to them, and their marriage was terrific. Mum can now sit back and enjoy her children, grandchildren and great grandchildren.
Me, I was married when I was 24, again at 43, and again at 59.
A sucker for punishment ????
