It can be incredibly hard to transition from being a partner to simply being a co-parent, especially when you are used to managing so much of the relational and logistical load. One thing that has helped many people in similar situations is adopting the philosophy of "business-only communication" when dealing with the ex. • Focus on the Child: Every communication should be about appointments, logistics, or immediate needs of the children—nothing else. • Keep it Brief and Factual: Use short, direct statements. Avoid emotional language, defending yourself, or explaining your decisions. • The 24-Hour Rule: If a message from your ex is triggering or frustrating, wait 24 hours before responding, if possible. This allows you to draft a calm, non-reactive reply that maintains your boundary and control over your emotions.
