I’m not laughing at you, I’m just depressed and hurt.

I don’t think the other party means to hurt you. If you refuse without feeling, you really don’t mean to hurt you. But your words seem to be accusing the other party, or showing contempt, and you have misjudged the other party’s feelings. Obviously he was not wrong and did not provoke you on purpose. He just refused frankly. As a result...it seemed as if he had done something to you, and everyone would vomit blood.
