No, Sugar. You needed to say what you said. You sound a lot like my H. He tends to stuff things down when he is upset about something just to keep things "smooth", but eventually it builds and then he blows (not always on the same topic). It's not good to keep things inside. My H's parents used to do this as well. They taught him it is better to not make waves, and to sweep things under the carpet. WHat happens is that those things don't really go away and they get worse.
I'm proud of you for telling her how you feel, and I'm glad the OW will not rent that house.
Drama ensued. That's fine. You did the right thing, and you get to continue to do the right thing. Whether the rest of them do remains to be seen.
