Boys always text girls late at night until they go to bed, but never contact them during the day. What is the mentality of boys? What should girls do? Should I ignore him?

No, misunderstanding is wrong. That boy really likes that girl. Even if he has a girlfriend, he sends text messages at night not only because he is bored or bored or empty, but because he has that girl in his heart. He ignored it during the day because he had a girlfriend and was afraid to fall in love in broad daylight. In fact, he has that love for each other, but it's hard to say. This is so-called silent love. Girls can try to ignore him for a while, in order to stimulate his love, let him say that he loves her, and then break it, and he will soon fall under her authority, or find time to talk at night ... I hope it will help you!
