Always ask for what you need. Your partner cannot read your mind. And that angry look your giving them may not convey what you're hoping to convey. Talk about it. Give your partner the benefit of the doubt.
Co-parenting is a cooperative relationship. When one of the partners decides to be uncooperative it changes the dynamics. However, as a positive parent, you can be the bigger partner. Choosing the positive is about every aspect of your life, and your kids are the most important relationship you can manage.
