I'd have to say that I hate being an adult when break-ups occur.
I was a single mom for most of my adult life, dating is already complicated in that situation. But when you have to deal with the heartache of a fresh ending while overseeing science fair projects and healthy meals when all you want is a vat of ice cream... It's tough. I would have much rather stepped back in time to being cared for than the caregiver. After two or three such incidents, I decided not to date anymore until my son was out of school.
