My brother has been married to his second wife for 12 years and has a 10 year old daughter who I am very close to. My sister in law is a cleptomaniac and a pathological liar. I feel like I am the only one who can speak to my brother about getting help for her. We are very close in age, but his wife and her actions have caused such friction in our family that no one wants to rock the boat and cause more problems for my brother than we know he all ready must deal with. I am worried about my niece and the horrible dysfunction she is witnessing and how that must be effecting her. My sister in law also has an addiction to prescription meds and has had a past of beating up my brother if he doesn't forge prescriptions for her. She says she trusts me and loves me so much, but she is constantly lying to me and others just to hurt us. Something needs to be done and I think my brother is just emotionally exhausted and doesn't know how to ask for help. He is staying with her because he doesn't want to have a second divorce. I feel like it's up to me, but what can be done?
