KIBS… She clings to her past

Hello Dr. Innocent I want to thank you for the advice you are giving us. It has really been of help! However, I have a big problem. There is this girl that I like but she is still a victim of her past relationship! She is afraid of moving on and she still wants her ex-boyfriend back but the guy has moved on! Doctor, what should I do to make her see what I am seeing? She likes me but she is confused.Fred UNILAK
