Any adult children of divorced parents?

I’m asking those of you who were already adults (or even teens) when your parents split.

When your parents split up.. was it pretty final from the get go?
Was it ugly and hateful? Did they split up and then get back together and then split up again? Were there long periods of time where they made it seem feasible that they were going to get back together? Did you ever expect them to divorce?

Just trying to feel out what is the “norm.” My parents have been separated for almost 2 years now, but lately they seem to be hovering closer and closer to getting back together than ever before. I’m trying to do my best to protect my younger sisters from a lot of unnecessary confusion, but I’m pretty confused myself at this point.

If you’re comfortable talking about it, I’d like to hear your experience.
