As each year passes the great yearning "To go back" with the same knowledge you have now and correct the past grows.
Everyone patiently waits for "their moment." Some are so hesitant to take it and and painfully watch as it passes them by. Others are too stupid to see when a gate opens for them. Then there are others, like me, who have it stolen from them!!
I was in love deeply with a 10yo when I was 19. That isn't even bad a 9 year age difference when you really think about it.
We were friends then started flirting with each other as any relationship starts. Within the year we were kissing and hanging out more. A couple times even saw each other naked. Then I turned 20 and had a decent job and a vehicle. She was in school and I used to help her with her homework when I had the chance. We had great chemistry and I truly believed we were made for each other.
Then a family member catches us kissing and tells her mother. Then everything falls apart and her mother takes her and moves away to another school district and far away from where I was.
Granted, she did give me a warning. If I saw her daughter again she would call the cops. In that regard she let me off easy but we effectively had a relationship for a bit over a year with no squarrels or bickering or physical/emotional violence (As everyone else in their so called "adult" relationships had)
She took her from me. Even today, when I am many years older, I have a deep hatred for her mother.
