Everyone loves a good romantic comedy every now and then. It’s nice to think about a universe in which the most unlikely people wind up falling madly in love, presumably living out the rest of their days together. But let’s be real: Not every one of those rom-com couples would actually last. In fact, most of them probably wouldn’t make it very far beyond the end credits. These are the rom-com relationships we can pretty much guarantee went down in flames right after their fairy tales ended.
