Maybe you had a childish thought, but I don't think you need to take all of the blame for what went wrong in that interaction. Your first text doesn't seem like something that should warrant that level of hostility from H. Maybe he had a guilty conscience about his own rudeness and childishness to just drop your D at the curb and decided the best defense was to go on the offensive.
