Children are like sponges. They see everything and their home environment is a massive influence on their formation.
Feeling trapped in your marriage is an awful way to live. You do realise that marriage is a choice, right? You can choose to stay or go, but ultimately know that this is YOUR choice. Your life. You are a grown adult with full autonomy over your choices.
What do you want for your daughters? Do you want them to see that a mother/wife role means you get treated like a second-class citizen / domestic servant by the man they marry? That you have no choice other than to be unhappy and trapped into a life you don't want?
Think about it.
I chose to end my marriage and raise my daughters away from the influence of a total misogynist who made my life a misery. Yes, it was hard, and goodness knows I stayed way too long when I knew, deep down, that I was on to a hiding to nothing. I've never regretted it for a moment.
Never mind the expectations and cultural "norms" of your background. You're in the UK and it's 2025. Let them see that you are a strong woman who's not prepared to put up with that kind of shit any longer.
Decide on your boundaries. Make them rock solid. Raise your daughters to be warrior women, and show them how to stand up to the patriarchy.
Also - sorry you're going through this. It's horrible.
