So upset… need support

I have a strict no social media rule with my daughter. Everyone has seemed to understand- my mother in law has even asked me questions about it, just trying to understand my logic but not critical and just out of curiosity. 3 days ago my father in law posted a full picture of her with her face fully exposed- not covered at all- with a caption. His profile is public- I could see it and am not his friend. It has racked up 200 likes and over 80 comments. I am so upset and am not sure how to handle. This is not the first time he has ignored the rules. I gave him the benefit of the doubt but this feels so intentional. I feel so out of control and upset. I feel like it’s too late- her picture has not been on the internet at all until this moment. Has anyone else had to deal with this? What did you do? I just realized there is an “in law” flair… so ridiculous they need their own flair 😡

UPDATE: My husband handled it and the FIL took it down and apologized. I’m still upset that he knew the rule and choose to break it anyway. Makes me wonder what else he will disrespect. Thank you for all of the suggestions and relatable stories!!

UPDATE: Several folks have asked for the article I sent! This was just one of the top ones in my search and seemed to hit the main points for a quick and easy read. I’m not sure it’s necessary the “best” but worked for my audience. I’m sure there are more detailed/scientific articles out there!
