Dear venir, dont see any good time or wait for the good mood of your husband. immediately bring it to the knowledge of your husband. if you are living in a joint family ask your husband to make immediate arrangements for the seperate family. if you are already in a seperate nuclear family, you don't be alone in the family after your husband left for work. you go to your parents house or search for job. In Pune it is very easy to get a job. Hence don't dely. Immediately inform your husband regarding your bil's behaviour. don't fear. God is there in your side. Hence take a bold step and inform your husband atonce. all the best
bring this to his attention immediately. He will be in the shock, but its your duty to get it to his attention immediately. Dont wait for the good time to talk, etc etc.These are the things that you should do immediately.
You have to tell all this to your husband..when he will know may be he will be shocked and stunned but then he will think and get to the solution of the problem..if you hide it from him then may be his brothers will tell him something fake which can create problem for you..
