Could you be burned out and in need of a two-three day getaway? Can you get away at all? I think it would relly help. I don't have kids, but I can imagine how hard it must be to deal with the noise during this stressful time in your life.
And why take care of the cat? Tell him he has to take his cat with him (unless you actually like to have the cat around.)
BUT you really should be proud of yourself. Remember that.
