As an adult don’t look to your parents to take responsibility for you. Take responsibility for your own life or your life will never feel yours. Until you take responsibility for your life speaking out in any way against someone in your family will feel disloyal. You may hesitate before recognising that something unfair or worse has been done. There will be family secrets. There will be whitewashes.
Where else do so many crimes go unpunished than as among members of the same family? Family often assumes jurisdiction over everywhere and everything.
The only person who can do something about this is you. Practice talking openly about your family and notice when you hesitate to speak.
If you take responsibility for your life your family may not thank you. What they continue to see from within their bunker will no doubt be different from you.
