Older sister in long term marriage with abusive H has made it clear she has no plans to ever leave. She is happy in very traditional marriage role with him in charge. But he is also abusive.
She has made it clear that absolutely no hint of criticism of him will be tolerated but he insults me in front of her and she says nothing. I have stopped confiding in her as I don't want him to know my business. I feel this is eroding our relationship and not sure how to stay close long term.
