Good for you that you have taken steps to implement Plan B!!!!!!!!!
I remember that every time I took one more step toward taking care of myself I felt as though I was taking another step away from my H. That made me sad at the time. I grieved what I thought were steps toward the eventual loss of my relationship with my H.
What I see now, is that given my H/XH's depression, the path I chose, was the only one available at the time that gave us a chance of reuniting one day.....and over the past couple months I have begun to see signs of my XH peeking out of his tunnel. Moving toward Plan B moves you toward the possibility of reconciliation. The universe will teach your H the lessons he needs to learn but this will take time. You are doing a very wise and loving thing by providing for your family's future.
