The GUY should be the one to call?

I think you should call him. You are over thinking it. Even if you did some how screw up over somthing so stupid, you are a girl. Getting a date is alot easier for you than it is for guys, because you just get to sit around and wait for someone to ask you. Or if you want to ask guys are usally pretty abvious when they like you. So dont stress it. If he likes you he will be glad you called, if he doesnt then move on. Hope i helped.
