my sil has dealt with her husband's occasional physical abuse and drug use for years. he claims he only smokes pot, but he's admitted to using cocaine before. he has friends who use cocaine. they've been married 8 years and have a 3-yr-old daughter. he also has bipolar disorder. previously, she has had to call the police for his violent outburst, but it hadn't been anything extremely serious before (any abuse is serious, but I'm just painting a picture here). recently, she was cutting vegetables when he went into an episode and was yelling at her. she asked him to leave, and he grabbed her hand with the knife in it and held her hand and the knife to his own throat yelling at her to just kill him. all this was in front of their little girl. my sil filed for an order of protection that was supposed to last for a year. a week later, she lessened the order to a peaceful contact order. it's been a little over a month, and he passed a drug test (I'm skeptical about it since my sister is a recovering drug addict and was telling me how much of a joke that is). yesterday, I learned she lifted the order. he has not been to any rehab. they've only been going to marriage counseling. I'm very concerned and worried about my sil and my niece. I know her husband is a smooth talker, manipulative, and dangerous. I do believe he doesn't want to be that way, and I know he loves his family, but he's got problems, and he needs rehab. I do not believe he's only smoking pot. it doesn't add up because of the extent of their money problems. i don't feel like it's my place to say anything to her, and even my husband doesn't know how to respond or help her, but he's worried about his sister. mostly venting, but I'd be happy to hear some advice.
