Iam very avengfull?

It sounds like to me that she reversed the anger. She was angry with you all of those years and she finally got the opportunity to get back at you, so not play the childish game that she has played with you when she comes back calling which she will act like you don't remember her and you are not angry with her and tell her about all the good things that has been going on in your life and let her know that you do not have time to meet her you are meeting your fiance for lunch.
