Hi L.,
It sounds like she is looking for a conflict. Don't play into it or it will just feed the problem. I would suggest going around her, and not confront her. As long as you maintain a good relationship with the children, they will always keep you informed and there is nothing she can do about it. As for the school, have your husband say your email is HIS secondary or home email address. If there are any other problems with parent/teacher involvement see what the schools policies are on tutor involvement. Find the detours for the roadblocks she puts up. But don't confront her, it will just cause more issues and fuel her to be more vengeful. And nothing makes a drama queen more upset then not getting the drama she was looking for. Hope this helps. Hang in there!
