Oh my!!! Yep, I would gladly throw out ANY plans I had if one of my girls were sick and xH seemed to not care. And you have every right to be furious for your sick D being with a sitter. That burns me. Life goes on for the WAS, doesn't it? Sick kids just can't get in the way...Hmph!

Does your X know that you would gladly have taken her with you?
