Went from divorced to coparenting like a team

My ex and I had a rough split 5 years ago. Lots of anger and fighting and our kids were caught in it. We were that couple where the kids had to relay messages between us. It got so bad that I finally said something had to change. We went to a coparenting class together, which sounds crazy but it helped. We had to reframe it: we're not married but we're still both parents. Now we actually text about stuff and sometimes even grab coffee to coordinate. My relationship with my kids is so much better because they're not stressed about our drama anymore.
