Keep your head up. I was the same way until my W left. I was constantly doing projects around the house, working, playing on the computer, watching TV, etc to be bothered with our kids. My kids are 6 and 3 and all of a sudden 3-4 days a week I was alone with them. At first I was scared, hell, I was terrified. But quickly, I realized how cool they are, how they constantly amazed me and it saddened me that I missed so much. Now I lead the charge on walks, bike rides, adventures, movie nights. My W thinks it's all an act (along with my entire personality change) but I really enjoy having them with me.
I am praying that your H has the same reaction at some point.
