Yep, me and my ex. Although we're not the norm amongst my divorced friends!
We separated 3 years ago, divorced 2 years ago. We were married for 17 years, having been together for 20.
Kids are now 18 and 16, so 15 and 13 then. This summer we went away for a "final" family holiday just the 4 of us before eldest goes off to uni. And it was great.
We've never stopped doing things as a family unit for DC birthdays and Christmas, and still have meals out with wider family (grandparents, uncles) for special occasions for DC,most recently for a level/gcse results.
We also have a shared friendship group who we both still hang out with , attending the same 3 events and parties,.not even with the kids.
We have a key for each others houses. He helped me fit new smoke alarms in my new house and fitted my TV to the wall in my new bedroom, his washing machine broke and I collected his washing and did a couple of loads whilst he waited for a new one, and ive helped him with gardening occasionally.
I also have a new partner who I met not long after we separated (been together 2.5 years now) and he and my ex get on great, and me and DP have attended parties at ex's house with the rest of mine and ex friendship group.
It wasn't always this easy though. Ex had a tendency to be very grumpy and passive aggressive through our marriage. Blaming me for anything that went wrong, expected me to know/do/fix anything that inconvenienced him, rarely showed me affection unless wanting sex, the usual bullshit misogynistic expectations on the responsibility for the mental load etc. All of which made me feel pretty shit about everything I did or didnt do. And as a result we had zero intimacy for many years before we finally split, existing in the same sphere as roommates basically.
Also when I first met my DP, (i told him relatively early on out of respect as we live in a small town and didn't want to hide) he was vile and accused me of cheating etc as it was so soon, but there genuinely was zero overlap and i had quite clear "evidence" of when I first met my DP. I know it wasn't ideal that it was so soon after and I understand why he was hurt, but luckily he did calm down and see reason quite soon.
I saw a meme once that said
"Divorce doesnt have to be the end of a family, it's a reorganisation" and that sums us up perfectly. We have a much better relationship as friends and co-parents now than we'd had as a couple in the last 10 years! He will always be my family and we continue to care about and support one another just not as a romantic couple.
So there IS hope.
But I guess it may only be like this/easier if you are both agreed about separation and there is no cheating/abuse that ended the marriage.
