Why does co-parenting feel like a never-ending negotiation?

The thing that frustrates me most is how every little decision turns into a debate. Weekend plans? "But they were *supposed* to be with me!" School events? "You can’t just *assume* I’ll cover that." It’s exhausting when basic coordination feels like a chess match.

I’ve been divorced for two years now, and the constant back-and-forth over schedules and responsibilities is draining. The worst part? The kids see it. They shouldn’t have to hear us argue over who’s "supposed" to take them to soccer practice.

What’s the one thing that actually made co-parenting easier for you?
