I think one, that your depressed, thus the sleeping a lot. Second, I agree with your husband - she is intimadated by you big time. Maybe you could find a third person to sit in with you as you talk to this woman and find out why she's doing what she's doint to you? I'm always one for "if you have a problem with me, let's air it right now and get it in the open"! I can't stand feeling like I'm being punished for some reason that I'm totally unaware of.
Myself, I would confront her about it...
