Why do i still have feelings for him if he just keeps hurting me over and over?

Exactly! Ask yourself that question and you will see that you need some adjustments in your life as it is not healthy to pursue someone who is not emotionally available. It just won't work, so you have to ask yourself why do I feel I need such a person? Then take steps to remedy that. Your loving him more than you love yourself and that has to change. People simply have different preferences. Nothing to do personally with you. Let him have that option and don't chase him. You keep hurting yourself over and over my clinging on to him and not accepting the fact that it's over.
