I don't get it, at least I tried. This has only upset me even more, since you're not bothered, why should I?

You don't need me, do you?
I am probably your first crush that can't make you happy. I am probably your first crush that seals his damn mouth too much. I am probably your first crush, that you can't be happy with.
David, wake up from your stupid dreams!
You wanted this to go somewhere? You, wanted this to go nowhere!
Besides, you told me not to go head over heels on you, I simply followed what you said.
I'm not complaining or venting my anger, I'm just feeling really, really upset after what you've said.
It's not the best feeling in the world.
