My dad lost his job a few years ago, has struggled to find much work since, and has since lost his confidence and has become paranoid. He can't hold down a job because he's very opinionated, plus he's getting older and doesn't have much work to show for it. He constantly argues with my mum over things and has been saying "You only moved with me to England because you wanted to meet an English man and run off with him". He has absolutely no proof whatsoever, and calls my mum a cow infront of my siblings and me. I don't know what to do. :/
