I don't know how your household is run at all, and I don't want to make any assumptions here, but I will....
I would think most women would have a reasonably difficult time living in a house with FIVE males.... Especially if she feels that she is responsible for all of the domestic duties. What a burden that would be.
For example, if you and the boys like to make messes, and she feels that she has to clean them up, there would be little time in her life for anything else. Know what I mean?
I have no idea if that is part of the dynamic. None of my business, but something to think about for a mo.
Oh, and if you are handy at all, prove it to her please! Thanks!
