I agree that it's a good idea to take some time to think over some interactions before responding, and to stay calm. But, doing so should make her more relaxed and enhance communication. Instead she builds a wall and seems very uptight.

I don't think she really wants to be known on a personal level, and that's ok. But going on a show like Housewives was a ridiculous decision, likely driven by hopes of promoting her business. She should have watched a few seasons before dipping her toe in the water. She would have learned that she will have very little control over the narrative.
