Sometimes, it's the best option to just walk away from an unhealthy situation, AC1201. What would you expect to achieve by seeing this boyfriend a final time? You cannot change the circumstances or anything that has happened - it's over and in the past, and we simply do not have that power to change the outcome of past events. Perhaps, the best option would be to concentrate on yourself.
And, I apologize - I got the age of your boyfriend from Glaxony's post when she mentioned an experience that she had, herself. So, I apologize. However, if the boyfriend is old enough to be charged with statutory rape, then he was old enough to "Know Better" than to fool around with a prepubescent child.
