Of course you did the right thing. Please bear in mind that is MIL i an alcoholic, she is a very sick woman and believe it or not, is probably doing the best she can. (as pi** poor as it may be). It's a blessing she's in rehab. If she can get some sober time, se may realize she has a serious problem and it is causing pain and misery all around. Bless you for helping them out ins spite of her venom. I'll be praying for the whole situation.
