"A hurt a guy who probably had feelings for me.played hard to get because i was scared that iam mot good enough for him.now i feel guilty and i feel people think iam egoistic"?"

I've been there too. I feel as if I'm not worthy enough so I give this guy a chase, and it ended up pretty badly. It's never right to hurt people but that doesn't ultimately turn you into a bad person. Reaching out and helping you both understand the situation better also helps. One mistake never hinders growth. People's opinions are not easily swayed at times but the only opinion that matters concerning you is that of yourself. Your own opinion. Guilt always comes but it also fades. I hope you and the guy talk things out and please always know that you are worth it. You are enough.
