Let the pain go

I might be a deep thinker, but if there's one thing I hate to think about, it is of a hurtful past. I forget my pain. I don't keep grudge. I move on.

Why remember a hurtful love when surely the love is gone? Just let the pain go. Or, forget the person who cause the pain. You know right? Love had did terrible thing to me too. That person caused me a great deal of pain that I didn't even cry because it just cannot be described. It pained, I remember how it pained. I never forget that feeling, but I forget the person who caused the pain. And there we are, still laughing at each other, singing each other birthday song on our birthdays, and quarrel over silly stuffs when we meet. But that's all. I forgot he caused me the pain. I just saw him as a friend. A harmless friend. Surely I will never come back to him ever, I knew we're not up to be something at that level, but I know we make good friends. I moved on. He doesn't cause me any pain anymore. just happiness because he can never be the cause of my pain ever again. As he's not inside my heart anymore. That's how I move on.

So I don't understand. Why pain over a person for a long time? Just forget it. We deserve better happiness. We deserve to be free from old wound. We deserve to heal. So why should you let the pain stay? Let it go and you'll see a better present. Proving yourself can be great revenge, surely. But to wish for nasty things happening to that person who pained you... We grow up, we become matured, we should heal. We move on.
