When Your Co-Parent Won’t Communicate Properly

I see this every week in my office. Parents sitting across from me, exhausted, saying “They just won’t communicate properly” about their co-parent. And I get it. You’re trying to coordinate schedules, share important information about your kids, make decisions together, and it’s like talking to a wall. Or worse, a wall that occasionally explodes.

First thing I want you to know: when communication shuts down between co-parents, it’s almost never just laziness or bad manners. There’s usually something underneath it. Fear, resentment, unprocessed grief from the relationship ending, a need for control when everything feels chaotic. That doesn’t excuse it, but it matters because your strategy needs to be informed by what’s actually driving it.

Is your co-parent the avoidant type? Going quiet, delaying responses, giving you one-word answers? Or are they reactive, explosive, inconsistent? These are different problems that need different approaches.

Here’s what I tell people in your situation: shrink the target. Make it as easy as possible for them to respond. Short messages. Single topics per message. No emotional content mixed into logistical requests. You’re not having a relationship with them anymore. You’re running a small business together, and the product is your children’s wellbeing.

Use text or a co-parenting app like OurFamilyWizard or TalkingParents. Everything documented. No ambiguity. No room for “I never said that.” Think of it like sending work emails to a difficult colleague. Professional, clear, factual.

Instead of: “Can you please let me know about Johnny’s soccer schedule because you never tell me anything and I’m tired of finding out from other parents?”

Try: “Please send Johnny’s soccer schedule by Friday so I can arrange pickup on my weekends.”

And then, separate what you can control from what you cannot. You cannot make someone communicate well. You can make the structure around communication so clear and low-conflict that their failure to respond becomes visible and documented, which matters if this ever goes to court.

Sometimes the real issue isn’t poor communication skills. It’s that one parent is using communication as a way to maintain control or continue conflict. If you strip away their ability to hook you emotionally, they often start responding more functionally.

Your kids are watching how you handle this. They don’t need you to be perfect, but they need you to be steady. Focus on that, and let the rest go.

Frequently Asked Questions

Why won't my co-parent communicate with me about our kids?+
When communication shuts down between co-parents, it's almost never just laziness or bad manners. There's usually something underneath it: fear, resentment, unprocessed grief from the relationship ending, or a desperate need for control when everything feels chaotic. Your ex might be a Reluctant Lover who withdraws to protect themselves from shame, or they could be stuck in the Versus Illusion, seeing you as the enemy instead of recognizing you're both trying to protect your kids. That doesn't excuse the behavior, but understanding what's driving it helps you respond more strategically instead of just getting caught in the Waltz of Pain.
How do I deal with a co-parent who only responds when they want something?+
This is classic Relentless Lover meets Reluctant Lover dynamics playing out in co-parenting. The more you pursue for communication, the more they withdraw. Your nervous system reads their silence as a threat to your kids' wellbeing (because it is), so you escalate. They read your escalation as criticism and shut down harder. Break this cycle by focusing only on essential, kid-focused communication. Strip emotion from your messages. Use platforms like Our Family Wizard that create accountability. And remember, you can't control their communication, but you can control yours.
What's the best way to communicate with a difficult co-parent?+
Keep it business-like and kid-focused. No emotional processing, no rehashing the past, no trying to get them to see your perspective. Think of it like coordinating with a contractor, not trying to repair a relationship. Use written communication when possible (texts, emails, co-parenting apps) to avoid reactive conversations. Document everything. Set boundaries around response times and stick to them. If you're struggling with the emotional weight of this dynamic, Figlet, our AI relationship coach, can help you process your feelings and develop better communication strategies between therapy sessions.
