Went from divorced and bitter to co-parenting respectfully

For the first couple years after the split I was angry at everything. Blamed my ex for everything, made things harder on the kids, didn't want her new partner around them. Got some perspective eventually, did some therapy, realized I was the one making this harder. Now we actually get along and can text without it being hostile. We coordinate on stuff. My kids are happier because the tension is gone. I miss being married obviously but this version of our relationship is way better than it was. Took work but it was worth it.
