I'm having a party on Friday and two of my circle of friends don't get along. Mainly because he (who is engaged) repeatedly makes unwanted sexual propositions to her.

Most people don't know about this though, and I don't think people in general think he is sleazy or understand the backstory. I invited her but not him. How do I explain it if people ask why he wasn't invited? She doesn't want to make a fuss about things and I don't feel it is my place to break her confidence. If I asked her, I know she would say to invite him and his fiance, and she would stay home, but that seems unfair, and I am much closer to her anyway.
