Hi Alone, I remember your situation with your family member. Nobody should ever ‘put up and shut up,’ everyone has the right to feel safe and happy. Your situation sounded diabolical with him, you 100% deserve so much more and are not the problem, but will find that an abuser will always try to convince you that you are.
There are ways to change your life, none of us are ever truly stuck but sometimes the solutions aren’t always obvious. Ring the helpline, keep posting.
