There are two general schools of thought about how to behave post-breakup. The first is the scorched earth strategy. Your ex is in the past, you want nothing to do with them, and they might even be a bad person. This is the favored strategy of people that are convinced of their own righteousness and moral certainty. Hell, sometimes it's the correct way to go about things. The second is: You loved each other once, maybe you can get back to liking each other. Sometimes things don't work out because of timing, or distance, or there was just a bad romantic match. Traditionally, this has been my view of things. Bella Thorne seems fully ensconced in the latter camp.
