I really like this guy and have since last year. I've tried to get over him but when I see him I realize that I still have feelings for him. Sometimes it seems as if he likes me back but I just I never give any signals. I'm really bad at sending signals that I like him and I can't even look at him. I guess I just get super nervous and I'm afraid that I'll say something stupid.(That's why I don't talk to him). Any advice?
