Dumbo, when it seems out of balance, that's she's doing too much for you, DONT stop her from doing something for you. That will only frustrate/aggrivate her. Let her do what she feels her duty tells her to. Achieve balance by doing things for her. It takes a couple days to find something she regularly does that you can do for her. That's what I did. It worked out really well since I felt better doing something for her and she was very appreciative for anything I'd do for her. Often times she was pleasently surprised.
Sounds like your going to have a great time!
