WHY do they....?

Why do guys say I LOVE YOU,
When they dont really mean it?
Why do thye say they wont hurt you,
But in the end they always do?
Why do they say forever,
But only mean for a little while?
Why do they hold your hand,
But thats when they break your heart?
Why do they say the will,
But never do?
Why do they say your the only one,
but yet theres someone else,
Why do they say "ill always be there".
But when you need them the most they are gone?
Why do they promise you the world,
But you only get a piece?
Why do they say every thing you want to hear,
But never mean any of it?
Why do they call to talk,
But still never listen?
Why do they ignore you infront of their friends,
But When its just him your the only one around?
Why do they try to make you feel better,
But they're the one that hurt you...???????
