Has anyone here tried Grey Rock Method? If so can you please help me. Thanks.

I’m am currently living (5 mths) with a sibling, who is always verbally abusing me.
Yesterday, I started to look for ways to try to avoid him. Thats how I found this method. Me and other family members (his wife and children) have realized, that trying to defend me doesn't help. No matter what I say I’m wrong! Sighs. Since I’ve lived here, I’ve try to sit at the dinner table less than 5 times, because every time I’ve tried he would start verbally abusing me.

So now I only eat starting behind, on the kitchen island. Yet, even though he can’t me, he still tries to argue with me. His wife told me, that he’s like that with everyone because he has depression. And to just ignore him. But I live in fear daily. To the point I only leave my room is to eat. Yet, he still argues with me. I wish I could leave, but financially I can’t afford to yet. I’m stuck here for a few years till I can get back on my feet. I have no where else to go.

Has anyone using the Grey Rock Method, been successful in ignoring your abuser? Do you think this method will work with him? He literally goes out of his way to put me down. If you had success with this, can you please give me some tips on how to stay calm. Because, so far every time he abusing me, I always defended myself. Thanks for helping.
