I'm going crazy because of him. I desperately need help, please?

By the sound of this it sounds like you have fallen in love with him. He should meet with you and if he doesn't or tries to get out of it, then shout at him saying that your not going to see him until thanksgiving and he keeps blowing you off which isn't fair! Take some action also if he does have the dinner with you and it goes really really well then tell him how you feel, right there and then. at that moment :) i hope this is helpful
