Polite and businesslike...go with that, SR! Don't let your emotions rule what you do here. It's so hard though when you see the pain that it creates for your DD, I know that. At least give yourself time to cool down and email tomorrow if you must. Remember, your goal here is as amicable a split as possible, that's best for your DD too. Btw, why did she want to reconsider the weekend splits? What does that mean?
