Actually getting along with my ex now that we're separated
Sounds weird but divorce was the best thing that happened to our relationship. We're not fighting all the time anymore so we actually can co-parent without constant tension. We text about kid stuff, she asks my input on school decisions, I helped her move last month. My new girlfriend thought it was weird at first but even she gets it now. If you're in the thick of it right now, it does get better.
This is actually really healthy to hear. Divorce sucks but sometimes it's the thing that finally lets people be better co-parents because they're not tangled up in the relationship stuff anymore.
