Weiss didn't tell him she was being sarcastic because she thought it was a bit too much of a stoop to explain that to him (it requires a surprising amount of humility to explain oneself). Pyrrha didn't tell him because she wasn't there and wouldn't have known. Ruby and Yang didn't tell him because they probably didn't realize that that was the reason he was hung up on Weiss.
