It broke

Her heart was joined by threads, 
Sewn to make it work, temporarily, 
Warnings were made, a little push and it'll all come falling down,
Like a pack of stacked cards,
It'll crash and nothing would help then,
She tripped, on a stone,
Smashing her head on to it, real bad,
She saw him before the beating stopped,
The sea of blood came running down,
She couldn't hold it, not the fake smile anymore, 
She broke, it broke. 
Threads flew open one by one, 
The hopes came crashing down,
She fainted, pretending to be asleep,
The blood never stopped following,
She slept for pretty long, she is now forever gone.
