A friend of mine is going through a divorce but she's always hanging out with the guy she's divorcing and it's confusing. She tells me it's still on.
Yes I see it very normal.
I wasn't married but I had a child with my ex and we've been broken up for over a year and we still hangout and even give him advices on other women. I think it's great that they can still have a good relationship. Not many people can do that so that's amazing.
