It is hard to do, but once you get the hang of it you really start to become a more fun, attractive person in everyone's eyes, not just his. Fake it until you make it.
What are you doint this weekend, start to get a plan together, and when you do go out, wear something hot, smell nice and be up beat and excited to do whatever it is you are going to do. Do not put all of this in his face, you do not have to, he will notice.
