You think of someone who barely thinks of you. You care for someone who doesn't even care for you. You cry for someone who doesn't deserve your tears. You love someone who doesn't even know you exist. Does it hurt seeing them together?
Does it break your heart knowing you never own them? Yes, love is pain for those kinds of you. The fact that they will never love you back, and the tears you shed for them. Don't hide behind the shadows of pain, cry for those who deserve your tears and smile for those who deserve your happiness. For true love will wait, and it will be great. Someone deserves you, more than those who left you.
