Quinsy: Just go to the police and relate the whole incident to
them but also tell them that you do not want to get your parents
involved. I'm sure they can help. Also, you are the victim, there
is NO way that the case will end with you going to jail.
If it proceeds, the legal case will be the state against devil
(police on your behalf vs devil)
as for stalking, if you have reason to believe it will happen or he
threatened to do so, then just tell the police and if it's serious,
ask for police protection or something..
