Breaking up, in general, sucks royally. But it's even worse when your longtime love seems to move on uncomfortably fast, and then gets engaged to their rebound after a head-scratchingly short amount of time. Oh yeah, and the whole world knows about it. But Cazzie David (whose ex is now the star of not only everyone's favorite TV show, but also an endless series of memes) and Selena Gomez (whose childhood sweetheart is engaging in incessant PDA) seem to be doing just fine. If you need a lesson in how to win the breakup, just turn to their Instagrams.
