Because you're stupid enough to ask this question.
tell him to leave you alone and tell a parent
You can tell if she is really destined to leave him if she moves on by opting for another boyfriend.
tell her shes about to die.
Tell him you got her pregnant.
Just tell him he is useless and leave him.
Consult your boyfriend he might tell her to stop,other wise talk to her your self.
if she is happy with her boyfriend then leave her be but if you think that it will benifit her lifestyle or her happieness then tell her
if ur cheating...that means u dont need him to be happy. leave him and tell him the truth why
If this person is in your house, you should tell him to leave. If he refuses, you can contact the police. However, if he is in her home, there is nothing you can do about it.
you tell your sister that he was your boyfriend and to leave him alone and if she doesent if your sis is still at school tell your mum she is cheating on her homework or do something toy get her in trouble and she will stay away from him
Show them you are a beautiful and confident woman and tell him to back off and leave you alone.
If it doesn't involve her, stay out of it. If it does, threaten. What I mean by threaten is if he can't be honest, tell him you will leave him.
