I agree with everything Lee said. I don't think you should feel guilty (though guilt is one of those funny things... I understand how confusing it can be...) I also think you should move on. Honestly, I would do little to no contact for a while to let yourself heal. Eventually MAYBE let him back into your life as a friend, but I wouldn't go looking for him. Definitely don't limit yourself because you're waiting to see if someday ever happens... You have to take care of yourself here. Your happiness is your number one priority. And have faith in yourself and your self worth. Be confident, and you will find someone else and have a connection with them too -- it'll be different, but that doesn't mean one is better than the other.
