Similarly to yourself, I lost mine at 13. Back then I felt like it was a choice, but he was 17 and he was a working young adult wheras I wasn't even yet in high school.
I was with him until I was 17, we had a child together. He moved on to another 13 year old, he was a younger friend of her step dad. As I became aware of the situation I started to feel strange about his relationship with our daughter. Luckily he disappeared years ago.
But I'm petrified of the ramifications of he came back into her life because he is a bit predatory.
I was told I should consider pressing charges on him yesterday, it took up much of the night and a discussion with DH turned into an argument.
I am scared it would look like I was out to get him, which I'm sure he's spent years telling everyone anyway, I couldn't allow the chance he could try and use it as some sort of proof to DD how much I wanted to hurt him, when that's not it..looking back he had no business sleeping with a 13 year old, and even if it was just me it would've been different, but it's somewhat of a pattern.
Adults knew what was going on too. Which always made me feel like it wasn't bad
