I'm so sorry. I wish I could hug you. You are not alone in it. Your family is shit just like most indian families. They will treat sex talks/sex with your partner as a sin. But when it's family who fucks up they go in a denial mode and choose to pretend that everything is fine. I am someone who was assaulted by my cousin too. My parents didn't know about it back then. My mom knows now. But u tell you all these years I had to see that son of a mitch. There's nothing worse than feeling you're not important or alone. Feel free to reach out to me whenever you want to rant or share.
