New boyfriend, and his ex. I really need some opinions.?

Confront her, and tell her that he has moved on and that shes too late. If shes a royal pain and a *****, she will continue to call him and try to sabotage your relationship with him. Be a ***** back and spreed rumors about her, but you might not be like that. Maybe you should tell him that he has got a week to make up his mind. Don't talk to him or see him for this period so he can choose. Tell him if he chooses you he has got to tell her to stop calling him, delete her number from his phone, and if she keeps calling - change his number.
