I think you've all got it wrong, I say this because of the lines:
"It was such a bad disguise" and "I saw you so we had a fight".
Personally, I think it's a post-breakup song, He and this girl had a relationship, and she broke it off, and acts like it was nothing, and it hurts him because he really wants to be with her again, but she won't let him. He keeps trying to be nice and kind to her, to win her back, but she won't have any of it.
