Most of my relationships are flings. I had my very short-lived (probably best) relationship this summer, that was amazing as it was happening but ended badly because well..we were both still in love with our ex's. Only problem is, he dumped me for his and it's literally impossible for me to get back with mine . It's shitty though, I'm noticing the older I get the more flings people are having. I think they don't work out because they're almost always after a bad or meaningful breakup and those fling-people tend to be expected not to last, they're those inbetween people.
