Found out my mom sh*t talked me and announced my pregnancy at 9 weeks to her friends

At my baby shower there were blank ‘notes for baby’ tor people to write on for my son to open when he turns 18. My moms best friend wrote something like this. This is a summary of what she wrote and it’s written to my son so I’m sorry if the wording is confusing: “dear baby- your grandma (so my mom) was complaining to me about your mom’s (meaning me) mood swings and irrational behavior, and I said maybe she’s pregnant! Then the next day, your mom told your grandma that she was pregnant! Your grandma told me she wasn’t supposed to tell anyone but she told me anyway. She said keep it a secret! Anyway, I’m the first one to have known!”

Would you be bothered to know your mom was complaining about your mood swings and irrational behavior and gossiping about you, and shared news of your pregnancy the day after your told her? I specifically asked her not to say anything because our town is very small and word travels fast, and I told my mom when I was only 9 weeks along. I wanted to tell my grandma first and I was going there the week after.

And the irrational behavior and mood swings she’s referring to was when I told my mom I’d be spending Christmas with my in laws instead of her and she flipped out and screamed at me for an hour straight on the phone and told me she hopes my future children treat me horribly and she wishes she left my family instead of my dad. Lol

I’m close to cutting her off and this might be the final straw. I just don’t know if I’m being dramatic about it.
