Values are what bring distinction to your life. You don't find them, you choose them. And when you do, you're on the path to fulfillment.
I have lived this story for 18 years. I strongly suggest that you and your hubby see a counselor who is experienced in this area. If you don't have steong boundaries, entitiled parents become even stronger entitled grandparents. It will make your relationship stronger when your husband hears from an expert that her behavior is not acceptable, then he isn't in the middle and you are not the "bad guy." Trust me on this.....it will be worth every penny and do it before the baby comes. My MIL pulled some stunts in the hospital when my children were born that were awful. Plus, it will be harder to get to appts with a newborn.
