I am really good at this situations. I advice you to just ignore her. And I am not saying to quit being friends with her. if she brings up the topic just say ok to her and try to slightly avoid the topic until she gets it. Then probably she will act like she's mad but it just will be because she wants you to do it. But just be firm. It's not like you are stabing her on the back. You will keep being friends.
