My BILs wife left him a few years ago for another man and is now remarried. His family all pretend it was an amicable split. He has since blown all his divorce money (house sale approx 100k) rents and is barely getting by. He is a big drinker 3 bottles of red is normal. Other BIL and him drank 9 bottles of red between them on Christmas day both still standing. Turns out BIL has a coke addiction. His family have their heads in the sand. BIL is a mess, lost weight, is not eating, i've raised issue with MIL, she thinks he had an overactive thyroid. What can i do to get through to them and him. BIL and I are not close.
