No need to apologize. Illusional is his usual grumpy self. In some cases u just have to ignore his behaviour. He has some good ideas, but in this comment i think he had a little to much alcohol. Just playing with you illusional.
It is true though. Many students have crushes on their teachers. I'm not sure why it happens. Most of the time its looks or as you said its his personality & smarts.
Just as long as it never goes past that student - teacher relationship, its okay to have a crush. Just don't let it develop into something fanatical.
