I personally think it BIL would be a great person to talk to your son I just think your H will flip out. In your earlier post you wrote that there was a divide between the two brothers and clearly as you have described above they have used different means of coping. It just seems like your BIL could be a big trigger for your H.
At an alanon meeting recently we were talking about how we used to judge people on their outside. How you could tell if a person was messed up if they were unkept or had missing teeth or maybe smelled like alcohol but it turns out the people we really needed to worry about were the ones that looked good & clean.
