I sent my response to her questions on the 19th, she responded on the 20th saying she needed time to think about 50/50. I thanked her for her reply on the 21st and told her I'd be picking the kids up this Friday.
Be prepared for the possibility that W may corral you into 'discussing' the 50/50 this Friday when you pick up the kiddos. Whatcha gonna do then? You don't want to look silly and flub your lines in front of W.
