I have this crush on this guy back in college. I see that he tries to say hi to me but I was too shy that I was ignoring him instead. Since then, he does not make an effort to say hi to me anymore. He has been ignoring me too. Worse, he thinks I hate him. It has been 2 years since we graduated and he's still my crush. I want to make things right so badly. If I add him on Facebook, will he accept? Won't it be too late to apologise?
