I know a girl who has only met once and is not a friend. Now I want to invite her to dinner. Should I call or send a text message?

if you make a phone call, you must. Generally, texting is about people with close relationships, men and women friends, etc. It is too abrupt for you to send it the first time. It will be more prudent to make a phone call, and let him think that this is a "banquet" as much as you attach importance to it, so he will attach great importance to it. In case you text her, she thinks you're harassing her, not only not coming, but also hating you. At dinner, you showed your gentlemanliness again.
