Nope, you were polite, straight and you made it clear that this coparenting thing must work both ways... I know you wouldn't push her to cancel the trip but granted all the sh!t you have taken from her it's good that you let her know that there is an end to "abuse", "if you push somebody hard enough he is bound to push you back...". Keep it "clean" and clear. Set your boundaries. You have many many years of interaction to survive through. Love K
