Dear Kaouther:

You are welcome. Now that you explained a bit more about the professor, I feel strongly that you should not join her and that man in any personal context. If he is teaching in a university, you can sit with the other students, your friend included, and listen to his lecture. But joining your friend for a date with this man, a married man- that’s a mistake.

Reads like he wants to have sex with her and she wants you to help her by being present so that he doesn’t try to have sex with her. Reads like he wants to have sex with her and she wants something else from him. Better you don’t accommodate such interactions between people.
