And remember, how you say something can be even more important than what you're saying. It won't be easy, but strive to avoid making accusations and getting upset. If it helps, view your ex as a business client. You need his or her help if you're going to accomplish your goal-doing what's best for your children. So be respectful as you attempt to close the deal.
Communication is the lifeblood of every successful parenting team.
So please, dad, for the sake of your children, just be honest, swallow your pride, and talk to each other.
