Every time it breaks, there is a chance for something new: a new understanding, a new experience, a new love. It's like a system update: it hurts, but then it gets easier and even better.
And yes, the heart is not a calculator. It doesn't always understand when to stop. It loves, it hurts, but in the end it always comes back to life with even more strength.
So don't worry when your heart is broken again. It's normal. It's part of the process. Just keep some chocolate on hand and don't forget that a broken heart is not a death sentence. It's just an excuse for a new beginning.
