I think you have already said this to her in many different ways. It's kind of like when you have told your child many times NOT to do something or what you want him to do....and then you decide enough is enough and you finally give him the consequence. No need for another talk, just do what you have to do....start becoming your own person...an attractive, confident, fun, passionate, sexy man that doesn't depend on someone else to be that man. You have had sooo many little talks with her ....didn't you just tell her that "enough was enough"?
