In the middle of the night, my girlfriend sent a text message saying that she couldn't sleep and was homesick. I comforted her, and she stopped talking or fell asleep.

1, maybe she fell asleep, because your words reassured her.

Maybe it's because your words made her more homesick.

Maybe she wants your company and is afraid to say it.

Maybe you should call her.

She won't be so angry, because giving you information in the middle of the night shows that she trusts you and hopes to get your comfort and a feeling of peace of mind from you. Don't think too much after you do it. Girls are not as fragile and stingy as you think. You can send a text message to care about it, or send a text message to tell her that she can't sleep in the future, and she will come to you when she is homesick, and you are ... girls like this little warmth best.
