She's giving me mixed signals?

well, I know that I sometimes send mixed signals. I get a new guy friend, find out how amazing he is, and love to talk to him, text him, message him and such. then I realize that * oops * HE LIKES ME. I don't like him ... so I start to become more standoffish. don't reply to his text. block him from my wall. only talk to him about things that aren't personal. stuff like that because I DON'T want him to like me. that's just me. every girl is different ... just see what happens dude (:
