How can guys do this?????

Why are all guys the same?
and that whole myth true.
Guys DO only think with their d***s!
Why is it that you can think so highly of a guy
and be so in love with them and they can say the same to your face, then they can go behind your back with another girl?
Why is it they do not care bout your feelings just that their getting wat they want?
Why is it that a girl can sit here crying while he is out with another gurl, not even caring bout your feelings?
Why is it that they can mean so much to you, and you obviosly so little to him?
why is it that one day you can be their best friend, and the next they do not wanna talk to you?
Why is it he can tell you he loves me, then goes and tells 3 other girls the same story?
why is it he can take your heart, then turn around and break it?
Why is it he can take my hand, then walk away from me without any remorse.
Why is it they can make a promis, they can not keep?
Why is it that i love him so much when he hurts me so bad?
