One day,

One day, you'll remember the girl who loved you so much that she forget to love herself.  You'll remember that she loved you so much until she forget what should she deserves.  You will remember her when you wake up and that time she will be the one happy with someone else.

One day, you'll  see her happy and contented with the life she have when you left her.  She will thank you for letting her go and for making her realize she worth of something so much better, that there is someone out there who is willing to be with her no matter what happened.  She will look into your eyes with no feeling for you at all.

One day, you will regret losing her.  You lost the girl who did everything for you.  You lost the girl who was always there for you when no one else is.  You lost the girl who stayed by your side even you always hurt her.  You lost the girl who tried her everything just to make your relationship works.  You lost the girl who tried to understand you when she needed you but you were not there yet she's still loving you.

One day, when you see her, you will feel like you've been stabbed in your heart a millions time for giving up on her.  The girl who stood by your side even if you don't appreciate her. You've lost the love that she loves the most.  And when that day comes, no matter what you do, no matter what you say to her, it will not make sense because she was already done spending years of her life trying to make you love her as she loved you... But you didn't.
