So you saw through him and he made himself scarce, big surprise.

I agree with the above posters; cut all lines of communication. Your script is great, memorize the best bits for if you happen to run into him unexpectedly. Then again, a simple "F***off!!" might do the trick. I have self esteem issues too, and it's so effing easy to be talked out of what's good for us by some jerk. Good luck!
