Dearheart, you were a child! How were you to know what to do?? You were not mature enough to decide!!! There can be no right or wrong to this question, sweetie, because you were just too young. You should NOT beat yourself up about this now. You should NOT feel guilty about this.
He was and probably still is, a vulture. He was luriing you into what would have been a very dangerous situation -- and thank God you knew it!!! Thank God you didn't trust him!
No one knows if he has 'done things' to other young girls or not. But it is NOT your fault because you didn't say anything back then!!!
Please don't feel guilty. BUT -- if you see him attempting to do anything like that NOW -- make sure you either grab him & knock him over the head (kidding) or get someone to hang onto him til the cops arrive!
I wish you the very best, my friend. Take care and God bless!!! Hugs, Lee
