Empty Space

2 years ago I was involved with a guy I loved for a long period of time. I loved him through ALOT and I seriously mean a lot. Yet we ended due to domestic violence. I couldn't physically and mentally take any more of the pain. I tried to date since but they all end fairly quickly. Recently I've been having feeling as if I'm empty and thinking about the good times I had with my old ex. I can still hear him call my name and say babe I love you. But then I would go to his IG page and hate him all over. Why am I going through this and how can I get rid of this feeling? .....
