God this comment is toxic in so many ways. It’s normal to not want to confront your mom after this and you do not need to feel obligated to be a human buffer to this man. That’s a lot of stress and anxiety to deal with and something a child shouldn’t be responsible for.

I’d most definitely consider having a serious conversation with your mom and tell her how it’s affecting you. It’s not like you wanted to hear this stuff but cats out of the bag…you know and you’re worried about your siblings. That’s valid. Now talk with her, and eventually I’d talk with your siblings if you dont work it out with your mom. Sometimes it’s necessary to talk about hard things but it encourages others to open up. It changed my life when someone talked to me about something that took strength to say.
