So I dated this guy for 15 months, and then we broke up when I left for college, about a month ago. We got back together for like 2 days this week and then I dumped him because he called me a and a bunch of other crap and he was acting like he was the boss and I was the slave.ever since then, he won't leave me alone and is begging me to come back and all that crap and he is guilt tripping me saying I never loved him and how I was using him to find someone else here and how he will just live the rest of his life lonely without me and that I will read about him in the newspapers and just being stupid. I try to talk to him about it and he just won't let me go. So when I ignore him, he gives me more crap for not talking to him and says stuff like "bye forever," and "fine dont ever talk to me again," or, "i love you but you hate me." its really annoying and its stressing me out because I have schoolwork I need to be doing and he's always messaging me when I'm checking my email on a chat thing. He's always on when I get on and I'm starting to think he has no life other than staring at his laptop and waiting for me to get on so he can send me a message. I really don't want to talk to him anymore because I don't need to be dealing with this kind of stress because like I said, I need to be focusing on college instead of dealing with him. I just want him to leave me alone and get over me and find some other girl to be with. I'm so sick of him. WHAT DO I DO??
