<human>: My best friend who I will call Carl not so recently (in late May) mutually broke up with his girlfriend at the time who I will call Megan.

 Megan was just graduating high school and Carl had graduated the year before. Prior to this point they had been on and off for 2 and a half years. For the last few months of this Megan had been essentially dating him for a week, getting incredibly angry about nearly nothing and then dumping him and immediately going out and having sex with someone. I know all of this happened because not only was I present at many of their arguments but also because I was friends with both of them and Megan wouldn't exactly keep the fact that she was screwing around a secret.

 Well, after several of us friends of Carl had an intervention with him and told him we were tired of watching him be bullied by her he finally decided to break up with her and she agreed. 

Since then either he will text her randomly and try to win her back or she'll text him and say something to try and get him riled. I'm really getting tired of him calling me up in the middle of the night crying. He can do better than her, he was big in our high school theater troupe, prom king and one of the most likable people I have ever met. He's just too hung up on her and convinced that Megan is "The One."

Can you provide a brief overview of the text?
<bot>: Friends were on and off for 2 years, towards the end the girl in the relationship got extremely emotionally abusive. They broke up and now he pines for her constantly.
