Heartaches that ache

You didn't give me a heart attack, when you left
You didn't give me a heart attack, when you twisted the thread
You didn't give a heart attack, when you started a fire
You didn't give a heart attack, when you ignited the spark inside me
You didn't give me a heart attack, when you turned out be "you"

Why is that, my heart aches now
Why is that, my heart feels the physical pain
Is this the ischemia screaming?
Is this the muscle getting tired?
Or is this just my restless mind tricking me into something like this!

Yours
Heart that aches, aches
