Hey Missy, You sound like you have come a long way from the unfortunate events of your childhood - you also sound like a remarkably brave lady.
I echo the thoughts of the above respondants, in that it MAY give the nasty B*****d some sort of satisfaction and also MAY be a clue via which to trace you in the future, unless you are incredibly careful.
As a possible alternative, you may wish to do what a close friend of mine did years after a similar experience: She too was badly abused and there came a point that she had to 'exorcise some demons', so to speak,. She wrote a very lengthy letter that detailed all of the nasty things he did, pointed out how wrong he was, how it was NOT her fault and how she has got over it, grown up,done well regardless and had began to create a really pleasant and normal life for herself, which was what she deserved.
After she had exhausted all of her emotions in writing this she then ceremonially burned the letter, as a way of closing this chapter of her life. The psychological effect of doing this released her from the shackles of the past and she described the feelings as being "like a caged bird being set free".
She has moments of reflection every now and again still but, on the whole, she is really well adjusted and lives life to the full.
I have no idea if this will spur an idea that may work for you too but, either way, I wish you all of the luck in the world.
Have a fabulous Christmas and a happy life - you deserve it.
KInd regards
