Opinions from the outside world

I want to start by saying yes I feel the same way my husband does and yes I tend to get walked on. I know she isn’t paying me well and yes I know it’s wrong. I have a 4 year degree making $9. 50 a hour. I don’t do well speaking up for myself so my husband did it for me. Here are some screenshots my husband took it upon himself to send my boss this message. My question is, was it wrong? I need advice outside of family and friends. I’m so shaken up to even go to work to morning because I know I’m going to get yelled at.

EDIT: I’m in childcare and me and the boss are family if any of this matters. Also I know without a doubt a doubt I will not be fired. She NEEDS me. The place is struggling and she can’t find any help.
