well it sounds like you were a diversion from the real world to him. It is possible that he never actually committed and he may have broke ties because he found someone to physically satisfy his needs and he deleted you from accounts that she may now be apart of to keep from having to explain you to them. He probably only kept the gamer connection for a “just in case” method to contact you in the event that he finds himself between physical partners. I’m sorry and I didn’t mean this to sound cold, its just experience with a similar situation that that I’m talking from. So I feel confident that he didn’t make the same emotional investment that you did and you only got to see the part of him that he wanted you to see. I know that it hurts but that is a chance that you are going to take with any long distance only relationship.
