Emotional abuse. He would ask me to pay.

A guy from my school abused me everyday. I've just completed college now and he still abuses me. He keeps calling me 10 to 20 times a day. When I talk to him some day he drains my energy completely. I dont know what I can say will explain it as it not physical abuse. When I was sick of him and I finally started talking with him he used to neglect me. From calling 20 times a day to 0. He says that I'm different and not like other girls. Im strange.
