Zelda, cheer up! People change. The girl/woman you knew 15 years ago must not necessarily be the same woman now. Chances are, she has changed. So think positive, and don't count on 15 y. old info!
It just occurred to me, perhaps you have changed now. This time, you won't be annoyed (if I got it correctly) by her, you might just jell at her, so that she never calls you again. And runs away if she accidentally sees you on public places.
Murphy can't be right all the time - it's against Murphy's laws!
Edit: now going to sleep!
