You never met this guy and it's been three years since you communicated?
What do you mean by "move on"? You haven't been dating in three years or you haven't really let go of the fantasy that he might come back into your life and be close again?
I don't really understand the relationship you had with him. You said you met him, but then you said you didn't meet him. Was it one of those on the phone/internet friendships that felt really close?
