Hey Brit! I'm home w/ D10 today as she is coming down w/ something. I am certainly not the one to tell you if you are doing things right or not. I have a heard time not inviting my H to dinner when it isn't his night w/ the Ds. My C pointed out that it is really hard for him to say no. I try not to invite him to do things outside of the house. If he plans something w/ the Ds I make the assumption it is without me. I think your W helping you w/ the house is very positive. At the very least it shows that she is willing to be your friend.
