When I look at this person intuitively, I see someone who feels his purpose is not clear. His intentions change from time to time. He focuses on outer world issues more than on his inner self. People like this change with the wind. There is a 50/50 chance he will come back but not for good. This person needs to mature. While he avoids emotional commitments, he ignores how his aloofness affects others. Based on what I see psychically, my advice to you is unfortunately, not to put too much energy into having a long term solid relationship with this person. Focus on other things so you will not allow him to hurt you. You will be hurt more by your wishes and expectations than you will by his on again off again behavior. Don’t feel alone. He does this to family and friends as well.
