I was 25 when I met my wife. She was 19. Totally normal.
Of course, I was no youth minister.
Very similar story here but I was a 20 year old youth leader (not a trained minister or pastor). Met a beautiful girl when she was 14. Kept my eye on her and when she was 16 we started dating. I proposed to her when she was 17 and we married a week after she turned 18 (she picked the date). In many ways, she was much more mature than I. Happily married for 47 1/2 years. Cancer. I miss her more than anything. Our only regret was not marrying sooner. She had a girlfriend that married at 16 and they are still happily married today. Have people changed that much?
