How do you deal with guys like this?

Why do most guys like to mess with girls heads???? I just cant figure it out... i mean if you really like someone you should be honest with them.... I dont think it is really fair to just leave someone hanging and all... If you say something and realize you have mad a mistake then tell that person... If your scared then tell them.... But DO NOT play mind games its not fair... anyway... how can you make guys realize this....How do you deal with guys like this?
You can't....some of us are confused....some of us are easily panic stricken and muddled....some of us are just plain stupid...and others are just a s s holes and enjoy playing mind games cause it makes them feel cool and gives them something to talk about...don't waste your time with that type...not all guys are like that :) - It's all about learning from your mistakes and getting it right in the end - you'll learn to pick out the wrong types - Although for some strange reason you girls always seem to go for the a s s holes first...my only solace is that what goes around comes around and someday they'll get their comeupance.How do you deal with guys like this?
You can't. WE DON'T CARE. Your only hope is to simply avoid this type of guy.
