What you described is uncomfortable, but truly not a pressing or serious matter. Shady people walk around at night. It happens. And nothing did come out of it. And it's nothing your friends could do about it.

Your friend had a personal problem, and it sounds like it was more of a pressing issue and personal problems are usually more relatable and demands more advice and opinion.

I wouldn't be jealous because your friend had more attention, and I wouldn't blame your friends for something they couldn't solve themselves.
