Co-parenting communication is impossible
Every time I try to talk to my ex about the kids she gets defensive or brings up stuff from the past. I try to keep things neutral and just focus on what's best for them but it always turns into an argument. I've been thinking about using one of those apps where you have to be civil but haven't suggested it yet. Any advice on getting through to someone who just doesn't want to communicate?
Set boundaries around what's open for discussion. If she brings up old stuff just say 'that's not what we're talking about right now' and redirect to the kids. Stay calm and keep it factual.
