taking the initiative to eat with you shows that he is willing to stay with you, especially when eating. Or this girl is particularly fond of food. You can take her to enjoy food, and of course she is willing to go.

why not talk to you? First, his personality may be introverted, and second, she may still be in the process of communicating with you, and she has not yet opened her mouth to talk to you. The third possibility is the speed and content of your speech, which may not be suitable for him and she can't understand it. Another situation is that there is something wrong with this girl's personality. She only has actions but no language expression.

if you play it by ear, act according to your own situation, and then continue to eat your food, you will definitely talk in the future. Just because you do it once or twice doesn't mean you can't talk.
