Communication tips for co-parenting with someone you can't stand
My son is 7 and his mom and I split when he was 2. We still don't get along but I've learned that keeping communication strictly about the kids helps a lot. I use that coparenting app (OurFamilyWizard) to keep everything in writing and organized. No personal jabs, no venting, just logistics and updates about our kid. It takes the emotion out of it and honestly makes everything easier. Might sound cold but it's saved us from a lot of arguments.
At 7 years old your son is probably picking up on the tension way more than you think. Not saying you need to fake being best friends but keeping it business-like in front of him makes a huge difference. I had to learn the hard way that bad mouthing my ex to my kids just made them feel caught in the middle. Now we keep conversations about logistics separate from anything personal.
You're already doing it right by recognizing it's about the kid and not about you two. That's like 80% of the battle. The other 20% is just not losing your cool in texts. I used to write out angry messages and delete them. Sounds dumb but it saved me from so much unnecessary drama.
