Hello there, I'm a very introverted person, actually I just have 4 friends. A days ago, a classmate of mine tried to befriend me, we chatted in whatsapp mostly about videogames like pokemon... However, he hasn't talked to me since that day (two days ago, if I recall correctly). I don't know why, he seemed to like it, and he also said he would help me with my shyness. I haven't sent him anything neither though, and I won't, because I don't want him to think I'm pesky or something worse. Besides, he's often online, it looks like he's forgotten me. Why does he do so, and what should I do?
