You can't controll her actions or words in any way. But you can control the way you feel. Let go of what she says and realize it's all so shallow. Petty small things make no difference, rise above them.How to get this girl to stop talking about me?
Just face her and tell her loud and clear (and in front of other people) to stop lying about you and talking behind your back about you. Call her a sneaky back-stabber.
Words mean nothing and are nothing.. Don't let words hurt you and or bother you. It's childish for her to be talking about nonsense stuff... so what if she is let her look dumb by herself don't lower yourself to her level.. she ain't worth it .. nobody is worth the sweat.. so like Mariah says shake it off..release yourself from all that drama.. stay away..from the people that hate and that are a waste of your space..
