I dont know if im the best at giving advice but.....here it goes...... There are some people in the world that just suck. They are selfish and self centered and they dont really have a good point in living. I think you met one of those people. I understand if you feel used but i dont want you to think of that so much. Hes is lucky he had you for one night. Dont be so hard on yourself. You were looking for affection in the wrong place. If he cant see something awesome in front of him then screw him. He sounds like an idiot anyway. You dont need to be around that. It sucks that he works with you though. I mean, you cant quit your job......that seems like the only way around it but the more you think about him the more its gonna affect you at work. You have to think about yourself instead of him. Hes nothing but a coworker and a descent lay.
