I share pictures with mine, relate the odd "this cool/cute thing happened while they were with me" via text, and she does the same. Once a quarter or so, we have lunch to talk about how we think the kids are doing with the divorce and otherwise. We'll usually talk for a few minutes on drop offs/pickups, but mine are of the age now where we do most of our switches by picking them up from school, and I don't see her in those instances.
She can still be weird and prickly and at times is hopelessly not self-aware in her texts or e-mails, and I just ignore those.
The kids like that we are civil and collaborative, so that's what I try to do. If I loved her still, I don't think I'd be able to do it -- at least not well or without pursuit -- so I'm beyond glad I don't have to try to pull that off.
