It just hurts knowing you give someone your all, you do everything possible for them.
Then they just leave like it's nothing.
They make it seem so easy because they don't care about it.
While you can't stop thinking about them. They're the first thing you think of when you wake up and the last thing before you sleep.
It hurts to cry your heart out, and knowing they don't care.
Missing them so much that it hurts but knowing they don't miss you back.
That's what hurts.
