So this mother in law to be went on a tirade via an email because she didn't like how she acted. And does it in a very rude and bullying way even going so as far to pretty much say she's not good enough for her step-son. And the reasons given are quite petty in my opinion. She should let her head drop from the sky and back to earth. I personally can't stand people like this. She was a guess and should be treated as such which would dictate that you're playing hostess and as such should at least let the little things slide such as sleeping in.
