I met my husband when I was 18 and he was 28. He proposed within 2 months. My parents wouldn't give consent, said I was too young, the age difference was too great, it would never last.
We married as soon as I was 21 (the age of majority at that time) and have been married for over 45 years.
So, 20 and 25? Pah. Nothing.
Jesus you're old!
