Spent the night catching up with some old friends didn't end up getting home until 7am. I walked in the house and WW hit me with 20 questions.
Did I sleep in my car? Is there an OW? What was I doing?
Just b/c your WW asked, you are not obligated to answer, and certainly not give details (even if short & sweet). Learn how to give vague answers without lying.
A WW has doubled standards. You will see how ironic it can be with the questions she asks. In her WW mindset, it is okay for her to have OM, breakup her family, stay out late, etc., but she doesn't want you having the same. If she is distracted by what you have been doing, that's good.
Always be on guard for her to hit you with something unexpected. She may be as ugly as sin one day and try to be best buds the next. The WW will call you out of the blue, acting all chirpy and wanting to go some place together. They expect to still be included in family trips, vacations, family and holiday celebrations, etc. they see nothing wrong with them partaking of the usual festivities, but don't you dare intrude into her secret life!
Have a prepared answered that fits several things. For an example: When she gets nosie with her questions, just look incredulous at her and say, "Seriously?!". Some things you might be able to laugh and walk away. Sometimes no response sends a loud message. Another example is, "That's not a good idea right now, considering the state of our M".
She is very curious about you, at the moment, which is great. She needs to wonder what you are thinking and doing. She also needs to see you are no easy pushover for her.
You said she had not left the MBD yet. Have you told her to leave? It is not uncommon for the WW to ignore it, especially if it means they have to sleep in an uncomfortable place. Remember, she feels entitled!
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
