Now breathe deeply. This is a piece of the puzzle in a very long process. Hitting her w/ facts isn't going to change the dynamic.
Focus on presenting this as not about either of your wants or needs or rights. This is about what is best for the kids and how you can work together with respect to achieve that. This is why you present the challenge this poses to the kids and ask her, given the concern, what is best. Turn it from a power struggle to what 'we' can do to take care of the kids as co-parents.
It may not work at first. You may have a while of sowing seeds. Patience is the virtue of any R, even if it is tense co-parenting.
