So confused

Karen
Ok me and this guy have been dating for 7 months and I am 14, him 15. We stopped because we couldnt understand each other. In the beginning he was really sweet and now he is so obessed with games and he easily gets mad while he is particularly playing league of legends. And there is always the same girl with him, and he doesnt like it when I get jealous. I mean she hangs out with him and gets along with him far more than me. I am a bookworm and he is a gamer. But we still love each other and he is thinking about maybe "giving me a second chance" I am starting to think it was right for us to break up. It is still hard, but I cant date him again. I mean we have nothing in common and I am always trying to be interested in his games while he never tried to be interested in mine. Only once and that was it. So right now it is either I am telling him it is really over and we cant be friends anymore or I will stay and perhaps he want to get back together and will be a better bf. Idk
