It hurts...
It hurts knowing you're smiling with her
It hurts knowing you are looking at her the way you used to look at me
It hurts knowing you're texting her the way you used to text me
It hurts knowing that you are kissing her
It hurts me more when you know that you had a chance with me
It hurts knowing you acted stupidly even with all my hints
It hurts knowing that you are possibly telling her good morning and goodnight all the time
It hurts knowing that I could have been yours
It hurts knowing that you don't notice me
It hurts me knowing that other girls did you dirty but I was there for you
And...
It hurts when you don't even say hi at school knowing that we text each other
It... just... hurts
