4 letter word, one painful meaning.

I pick up my heart, shard by shard.
I never knew love could be this hard.
I never know such a word, could cause so much pain.
or drive you so insane.
But, love is just a four letter word, that can shatter.
All you have to do it act like I don't matter.
Break my heart, and let me fall.
I'll wait by the phone, but you won't call.
I reach for your hand, but you don't grab mine.
I'll call you, but no one will pick up on the other line.
You say hurtful things, and laugh at me infront of your friend's.
I keep thinking "This is where it ends".
But I can't walk away, your my angel from above
This is all I know about love.
