You have to stand up for yourself and your D, no question. It sounds to me like your W is using your D almost as a hostage or weapon against you. I hate seeing that.
I don't think you are being unreasonable at all. I *really* suggest that all communications go through your L from now on. She thinks she can bully you if she talks to you directly.
