Again. You need to show her you have considered her suggestion. You need to focus on what is best for the kids, and not about what you want or what she wants. See how that is different. "I have some concerns that the arrangements' impacts on the kids. blah, blah, blah [insert your concerns]. I know we both want what is best for the kids. What do you think would be best?" Let her have her say. Then tell her you'll "think about what she suggested." Go away and do that. Then get back to her to show that you have thought about what she said, and if you have a concern raise it. Lather, rinse, repeat. It is about listening to each other and putting it in terms of what is best, showing that you respect the other's opinion and are giving it your serious consideration. And then do it. These can't be just words. You have to seriously consider what she says, then reply, ask her opinion, seriously consider what she says, and keep doing this.
