I think you should call a women’s domestic violence shelter organization. They will listen to your situation and help you strategize and plan. It’s really concerning to me that your family is gaslighting you like this. Why do you think they’re doing that? Like are there patterns of abuse in your own family? This is so objectively just a huge NO that I can’t comprehend how anyone could try to explain it away. I think I’d call a women’s org first and see what they think about contacting the police and how the police might be able to help if at all.
