YTA Your bf wasn't diplomatic in his phrasing, but he was right. Your parents were incredibly invasive, rude, and insensitive to him during the first meeting -- asking him why he thought the divorce happened, why he didn't stop them and so on... what the hell is with that? He has a right to be offended by their awful behavior.

I don't understand why he called you "noisy" (I first read that as "nosy" which seems to fit better) but I can understand his annoyance with your parents. He was only describing their undesirable behaviors. If you are offended at that, is it because you see his description as inaccurate or think that even though it is, he shouldn't be complaining about it?
