H came round to see the kids today and stayed for 5 hours. It was hard. I went out for just over an our to get some groceries. Made some lunch (H had some too) and then H put a film on for him and the kids to watch. I sat and watched some of it while flitting in and out sorting laundry. Then promplty burst into floods of tears when he left. I can't handle any of this at all.
