My brother is an arse and a bully who's shown since leaving his wife and three kids the very worst sides of his character. We've had a few spats, last night he was trying to boss me into supplying him with financial information that he could use against my SIL. I dug my heels in and said no - I knew he could get the information elsewhere so I just wanted to wind him up. I totally succeeded, he is fuming and has now also fallen out with my mum over this... I feel
guilty because my mum is now upset, not sure what to do!
