Sorry to hear what you are going through packer but you really do have to move on.. Whether you still want him or whether you think you can be together in the future you have to move on. Clinging on to this false hope is only stalling your healing process.
Just remember that a lot of us on here have gone through similar pain of some sort. And the best way to get past this is to not call, not talk, no contact! Just try getting busy and not looking for that special person.
Just like everyone says, you cannot change someone and their feelings - this is how he feels right now. Maybe in a couple of years he won't feel the same and by then you would have had the time to get over your feelings which actually allows you to be just friends.
It is absolutely imperative that you continue to not contact him and not respond to his calls and texts. Help yourself move on, so you can help yourself to maybe find that right person for you - there is no point going crazy over someone who isn't on the same frequency as you.
If you do not move on you will never Mr. Right - use this to help you move on. Nobody is ever too old for love, just give yourself a chance.
