i would in regularly inappropriately touch a girl from our neighborhood, i was around 13 years old and she was 8. i have really felt guilty and depressed about what happened and what i did. After almost 10 years i searched her on facebook to try to apologize however i chickened out.
yesterday i got a message from her asking if i remembered her and that she really felt good chatting with me as i am her old friend. i couldn’t help myself and i apologized without specifically say what for, she said that she didn’t understand why i was apologizing.

now i really know now what to do, i feel worse and ashamed.
should i come clean and tell her everything?
