I would say that they get bored, and where they were willing to put in effort (which all relationships require) at the beginning, they aren't now. Which again, isn't surprising. Even people who get married and think they'll be together for the rest of their life get bored and leave about half the time. I think that the trend is towards shorter, less emotional relationships, because nobody wants to get serious; everyone wants to have fun. Nothing that's not fun is worth doing. Who knows, maybe the next Tinder will be more like Uber.
