That Awful Ex-Boyfriend

“The awful ex-boyfriend who said our first night wasn’t that great, said he was sick of me, and even cheated on me with another woman… keeps trying to get close to me again.” My ex-boyfriend lives next door. And not just any ex—the really trashy one who even cheated on me. “A girlfriend? We’ve known each other since we were kids, so I’m just dating her out of obligation. I’m getting tired of it now.” Cheating wasn’t enough for him; he even talked trash about me behind my back to his friends. There was absolutely no reason not to break up with him. But at some point, my ex’s behavior started to get really weird. He kept clinging to me, annoyingly persistent, and then— “I’m not just the guy next door. I’m the ex-boyfriend she was crazy about, the one she couldn’t keep her hands off.” He even spewed that nonsense in front of the first guy I’ve had a thing with in ages. What the hell is wrong with you, Kwon Doha? We’re broken up now!
