Is it worth confessing your love on the Internet?

Once I had an acquaintance with whom we communicated on the Internet for several months, he fell in love with a girl who cosplayed a character from one of his favorite series, well, he admitted to me that he had been following her for about a year and dreamed of talking to her on the Internet, because he felt that he was in love, and then asked if he should try? I said I should at least try, but my advice broke his heart, she rejected him and called him a freak, then he got drunk and we didn't discuss it anymore.

If anything, the girl was very beautiful.
