You made your point without rubbing her nose in it. Yeah, I think she owed you an apology, but you held your boundary and you let it go. By not engaging with you and turning the conversation chatty, I think it was her way of conceding you the point.
Someday, she may learn to apologize without feeling threatened. Maybe not. But, by God, you shut her down, and to me, that would be every bit as good as an apology. At least for now.
