Depends on how you feel...

Firstly if you feel, disrepected then tell it how it is, tell her what she has been doing is not for you, it's not the type of friend you are after, so she either works that out and things will be fine, or move on, her choice.

Take over the power.

From there it should be easy, as she will apologies and see or move on...

Secondly, then be first and strong on that decision, if that is your belief in this friendship, ok.

As it seems to be the case.

No point wasting your energy on someone that is not worth it is there...
