Frankly, it's one's ego that is broken more than the heart.
What did i do to deserve this? It is pure heart-hurt. If it had been all about your heart, would you have said "how unfortunate, but what the hell, there's a lot more love to give than to lose", or something like that.
It's the head that answers back at breakups with the question mark.
Coping with a breakup requires more of head and sanity management than the heart healing. The heart is powerful muscle. It's primarily responsible for keeping the rest of our body parts functioning.
The art and sophistication of coping rests on the fact that the heart has a lot more love to give than what it has lost.
