I want to tell you that you are doing fantastic! You are handling things so much better. You are growing leaps and bounds.
As far as your H saying that a D is inevitable, he probably thinks so right now but that doesn't mean that it will happen.
My kids are what helped me make it through the roughest of times. I would look at their faces and say to myself that it is my H's loss. I have my babies and nothing will ever take that from me!!!
