So it's a really horrible situation, b-in-law threatened dh 3 years ago with violence, we were horrified / stunned and reacted by keeping the hell out of the way. Unfortunately this hasn't worked really and b-in-law was verbally aggressive to me today to the point that I was shaking and dd's were crying. B-in-law has anger-management issues and a reputation for being aggressive. B-in-law's mother is very active in the local church community and respected and her son is very close to her. I am so sick of this bullying and plan to visit her to inform her of what her son's behaviour. I hate confrontion but need to do something AIBU to go to her when it's her son who is causing the problem?
