Heartbreak is a very physical pain. It's opposite of the feeling you get when butterflies take over your chest as you fall in love, but heartbreak has a hint of familiarity. All of the butterflies in your chest that stayed with you for so long begin to push up against your throat. Your throat aches, and it's a very familiar feeling. The same feeling you got when you were so happy in love, so head over heels that you wanted to cry. But it's not just a feeling and the butterflies escape as tears and you can't stop crying because you loved when those butterflies took over your body and sent chills down your spine.
Love ends just as quickly as it begins.
I don't even know the lifespan of a butterfly because they always escape before I have the chance to say goodbye.
