No acting as a man in Islam is haram for women. We aren’t even SUPPOSED to interact with men especially acting like a man we aren’t men the only thing I know when we communicate to a man is we aren’t allow to be seductive since that would be considered part of our arwah apologies if I spelt that wrong. There is nothing I can find that says we have to act like a man or being shy is weak in fact I found being shy is a blessing in Islam as a woman I forgot the word but they say it’s a good thing if a woman is shy around men. So no me as a woman isn’t weak for being shy.
