That is nearly impossible. You can't be good friends with your ex (unless you both never felt anything for each other in the first place). My ex and I tried to be friends after our breakup, but that didn't work out. It's just a bit awkward because you had a past with them and you can't see them the same way. I personally am friendly with my ex rather than friends despite the fact I hate his guts. So don't exactly be friends... be friendly for now, and maybe in a few years from now (when both of you are dating someone else and completely moved on), then you can be friends.

I wouldn't know. I don't date friends. And the whole reason I'm with them is for them to be more than a friend so their is no demotion going on just a firing.
