So i just broke up with my ex coz he did not treat me right. He would never reply to my Texts and would always avoid meeting me. However he treats me like royalty when I am with him and when we are at school together and that's why I fell for him. But as it's the summer holidays I have seen him once and it has been non stop arguing which I cause coz I just want his attention. I am now getting close with this other boy but u can't seem to get him off my mind, I just feel like there is unfinished business between me and my ex..What should I do??
