My boyfriend said I was beautiful, with a good face and a beautiful face. Then I said what's the use of being beautiful, and he said it's certainly useful to meet a good man like him.

After reading your above description, your boyfriend said that you are beautiful, with a beautiful face and standard facial features, and you are a beautiful woman. Then, you said it was useless to be beautiful, and he said it was certainly useful to meet such a good man.

In my opinion, the conversation you described above between you and your boyfriend is just a little joke that you are flirting with each other. There's nothing wrong with that. Just be happy. I wish you happiness forever.
