Bruce is remarried with a baby on the way, so who knows what's going on there.
I think Demi needs to get herself together and start acting like an adult. Doing Whip-its and partying with her daughters is not how adults behave - it's just embarrassing. I'm sorry she's in pain, but this isn't her first divorce - it's her third. Time to put on her big girl pants and be a better example for her daughters.
