I ultimately decided not to send anything thanks to all the great advice from here.
The one thing I have to start doing better is ONLY "apologizing for things that warrant an apology". I tend to go overboard when validating and end up feeling horrible.
Great example, she has stopped taking care of the puppies altogether. On the days she was "supposed" to have them, I have not been able to get any "day care" for them so there has been a few accidents. When W found out she indicated "the puppies were pooping all over the place". Should I apologize, nope, out of my control in the near term. Did I apologize, yes. Feel like it was a mistake.
