My in-laws know about his drinking. My M-i-l talked with me for over an hour the other day. She know he is an alcoholic and she said how I put up with it for all these years. She also talked with my AH about getting help, etc.
My sister-in-law is very supportive of me and out kids. Of course it's her brother but what he is doing is unacceptable.
yes I have told them but they knew already. I'm glad I have their support.
