Never seeing or hearing from them again is truely the best way to go. However, if the person insists on showing up at places where you go, then there are some things you can do. First, tell the new target about your experience with the P, when he's not around. Maybe not. You can be sure that if you do, he'll try to discredit your information by telling her you're bitter or crazy, etc. However, I couldn't in good conscience allow someone else to walk blindly into that if there was anything I could do to stop it.
Another thing is that most Ps are addicts of some sort. If he's around and you notice he's buzzed, then get his vehicle description and license plate and let the cops do the rest! This is a big reason why we keep running into them. The law hasn't processed them enough to keep them behind bars. Do everything you can to give him the record he deserves. Or not...if he thinks you're doing that, then maybe he'll freak on you.
After reading and experiencing, I have been forced to the conclusion that the only effective way to rid your life of him once and for all is totally illegal! So, I play it the lame legal way and he keeps doing what he does best without missing a beat. New legislation is an answer.
Don't change too much because of him. Keep your heart red, but know that it can still happen again, no matter how much you think you've learned. Some are just too good at it.
