I'm sorry your husband has left. You are right--what you are doing is pushing him further away, so stop fighting about your relationship. Use this time while he is out of the house to make some adjustments. I'm glad you have the book, jump to THE LAST RESORT TECHNIQUE.
You have a lot on your plate with two small children while he has left. Are you working as well? Do you have any help?
It is going to be very important that you take care of yourself and that you DO NOT appear to be falling apart over it. You will need to do the best acting job of your life.
