My Best Friend is still friends with the person who SA'd me. What should I do?

A few months ago my friend at university set me up on a date with a friend of her's and unfortunately he assaulted me on the date. I won't go into detail of what he did, but I told my friend and she was horrified and very upset at what he had done and says she feels guilty for setting us up. The problem is that she is still friends with this person (I understand that that is completely her choice and I have no right to dictate who she can be friends with especially when she has known him a lot longer than me). She openly talks about him in conversation and invites him to events that we go to, and I try my best to avoid him and I don't say anything because I don't want to cause any issues within our friendship, and i know how difficult its been for her to navigate this stressful situation as she has told me this. Her friendship with him is also one of the reasons i haven't reported the assault, i really dont feel like i can deal with that process right now. She also tells people about what he did to me referring to me by name, especially when we make new girlfriends, to warn them of his behaviour. It's incredibly uncomfortable when i then have to meet these people because they now know something so personal about me. Its getting to the point where I don't know how much longer I can stay in the friendship with her because of this, her telling people makes me uncomfortable but she justifies it by saying she's just looking out for people, which I get because the thought of anyone going through what i did is extremely upsetting for me to think about. It's currently summer and I will be going back to uni in a few weeks and I feel really terrible because I love our friendship, she's on the same course as me but for my own mental health and trying to deal with the situation and heal, I really don't know if I can remain friends with her and continue to act like I'm not incredibly hurt by how close she remains with him, or pretending like im not terrified everytime im in the same room as him. I really don't know if losing the friendship with her and our closeness is worth it, the thought of not having her as a friend is the whole reason I've remained with her throughout the past few months after the assault. I've had a few other friends out with the situation tell me that I should cut her off and that they don't understand how she can remain friends with him after what he did and I'm starting to see their point of view. I guess I would just like some outside opinion on the matter and any advice would be greatly appreciated. thank you x
