That sounds assertive to me.


It sounds like you are still angry / annoyed with her for doing this and that there are some trust issues in this friendship. You have a right to feel this way. I might, too.


I am wondering why you are wondering if you were assertive enough? What else were you thinking of saying to her / doing?


In regards to your question wondering what you should do moving forward with this friendship, what do YOU want to do?
