One day, you'll remember the man who loved you so much that he forgot to love himself. You'll remember him when you wake up, when you eat, when you're about to sleep. He will be your greatest nightmare. You will be the one crying, and he will be the one happy with someone else.
One day, you'll regret losing him. You lost the man who did everything for you. You lost the man who has always there for you when no one else is. You lost him because of your ego. You lost the man who stayed by yourself even if you threw harsh words to him. You lost the man who tried to understand you when he needed you and you were not there.
One day, you'll realize that he was the one for you. The man who stood by your side even if you don't appreciate him. The man you choose to let go because you're full of pride. One day, you'll realize that the man you screwed up and left for another man, was the man who kept fighting and defending you when he hears gossips about you.
One day, you'll see him happy and contented with the life he has when you left him. He will thank you for letting him go and for making him realize he is worth of something so much better, that there is someone out there who is willing to do everything for him. He will look into your eyes with no feelings for you at all.
One day, when you see him, you will feel like you've been stabbed in your heart a million times for giving up on him. And when that day comes, no matter what you do, no matter what you say to him, it will not make sense because he was already done spending days of his life trying to make you love him as he loved you... but you didn't.
