how to get rid of a painful attachment?

highschool, i became emotionally attached to her since she used to hug me alot and listen to me. She told me she was gonna be there. But when I really needed her and was going through alot in my life she started leaving me and running away from me..it really killed me and made my problems worse. After 3 years, I still feel pain so I decided to msg her that she hurt me. Her awnser was that she was making me tougher to face life since I was to sensitive and she escaped cz the attachment wasnt healthy. I still feel really bad and have been crying for days..she didnt tell me she wanted to see me..do you think I should call her and tell her I wanna see her? Do u think that will ease away my pain by facing and seeing her? Or would it make my attachment worse??
