Wow, that really sucks. At this point, I wouldn't even care if I made her mad (unless you think she would go so far as to physically harm you)! If you and your husband are trying to work through your problems then maybe BOTH of you should confront her and tackle the problem head on. Something has to stop her... My God, she sounds horrible. I truly feel sorry for ya. And I hope you can get the problem taken care of very quickly. Best of luck to you.
