How can you break up with someone who's not even technically your boyfriend? Somehow we managed. But the definition of "breaking up" can be just as fuzzy as the definition of "dating" or "boyfriend." If by "breaking up" you mean still going out a few times a week and still hooking up, then yes, we broke up.
So -- what's the best way to take care of yourself after a "break up"? Get lots of sleep, go to the gym, and, of course, go out for drinks with your ex and ask out another bartender.
Nice one, Lar.
