To the girl who keeps breaking her own heart, start loving yourself more. Start realizing that you cannot fix someone. Start protecting yourself from inevitable heartbreak because the boy you think you can change or think will change for you isn't going to.
To the girl who keeps breaking her own heart, it's not your fault that he won't love you back. You love with every fiber in your body, but even all the love in the world can't change a person. It may have worked in the Grinch, but the boy you care so much about is not miraculously going to grow a bigger heart.
To the girl who keeps breaking her own heart, remember that you deserve to be the first priority. You are not a second priority, or a third or even a last priority. You are worth more than inconsistent texts and mixed signals. You are worth more than being "just another girl" to him.
To the girl who keeps breaking her own heart, remember that you are too good to be sad over someone who isn't upset at all that they lost you. You have to appreciate and respect yourself before someone else can appreciate you. Don't worry about being without someone, you will be okay on your own.
To the girl who keeps breaking her own heart, to myself, you are sunshine on a rainy day. You are smart, you are kind, and someday you'll understand why things never worked out the way you wanted them to. Someday someone will love you the way you deserve to be loved. But today, you will put yourself first and stop breaking your own heart.
