Me too. I hate confrontation. Especially when you know that all you're going to get are more lies. xx
He's a compulsive gambler who would rob his own demented mother. This may be a bit whacky but it really helped me. I went to meetings at Gamblers Anonymous (about my ex husband not my brother) to get ex help and save the marriage. (Can't be done I know now) but the gamblers have a meeting and their friends and family are in the other room, they were brilliant, really put me wise.
It might be an idea to go to a couple of GA friends and family meetings just to find out what they're capable of. I might actually take my own advice and go to a meeting with my situation now, see what they think.
So far as I am concerned the more perspectives the better.
