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?

He ignored this girl during the day, which means he has no time to talk to you at all.

But when he is alone at night, he will think of you, which means it is a good thing.

But it depends on what kind of person he is

When I use you to solve loneliness or loneliness, do I want to talk to you?

For whatever reason,

Leave him alone.

If it is the first kind, you are just his boring seasoning, and it is right to leave him.

If it is the second, it means that you still have a certain position in his heart. When he sees that you ignore him, he will keep looking for you.
