Hi HoneyPie, I've never been through this myself but I know it is tough. Hang in there !
My sis who has a young kid ( my 1 yr old cutie-pie niece) is currently going through a divorce too. She has moved to stay with me and I'm trying to lend as much support to her as possible - physically (looking after my niece), emotionally and financially. On bad days when that to-be-ex-bro-in-law is behaving like a nut-case, I really feel like throwing my giant pedal wrench at him to crash this NUT !

meanwhile, just hang in there. Here's a big *HUG*.
