my bro has 2 girls one of which he isn't allowed to see. and she's been adopted by another man. it's sad but he crossed the line with his ex by hitting her. i won't sleep alone in the same house with him and i'm bipolar too!!! he was committed once because he was planning for several months to kill our mother. he was convinced that she was evil and that god wanted him to kill her. some bipolar people project their anger on another. this is highly dangerous!!! be careful, please.
does he get violent? at all? even just breaking stuff...
this is NOT your fault in any way. just like it's not his. he's sick but you have to be careful with bipolar. it can get deadly. if you are scared of him then i would consider breaking away physically and possibly emotionally. i would hate for you to get hurt or god forbid your kids!
another option is to have him committed. but make sure you get the support of family and close friends. it will hurt to do it but it could save his life.
i will pray for you, your children and husband.
