Heartbroken

This guy I’ve known for years and started talking to again romantically this past year just cut me out of his life with no feelings or anything towards me. I wonder how someone could do that? How could someone be so cold after years of knowing each and building trust saying I love you, writing letters! And In a matter of what appears to be minutes, I mean nothing to this person. I have so much anxiety and sadness inside. I finally see how cold and icy the world is. I don’t know how I’m going to get through this but I know I will. I just want to forget him. I want this unbearable pain to go away. I can’t eat or sleep. It’s really got me messed up. Anyway..... love hurts.. really badly..is the moral of the story
