I am so sorry that it hurts so badly. Stay strong, it's going to be tough for a while. Someone on this site once told me the following and it resonated with me for a long, long while: "You never really get over someone who once meant so much in your life, you just learn to live without them because they have moved on and so must you." Just don't contact him. Every time you do you are taking a step backwards and will have to start all over again. I'll be thinking of you and sending you good vibes.
