What do girls mean by treating me like a brother?

It is normal for men and women to call each other brothers, but it is not normal for men and women to call each other brothers. It feels weird. Generally speaking, if a woman treats you as a brother, there are only two possibilities. 1. Reject you politely. If a girl usually has a good relationship with you, can get along with you and often go out to play together (not alone, but a group of people), it is pure friendship anyway. But if this girl realizes that you are interested in her, but she is not interested in you, then she will tell you euphemistically in this way that we have no chance. I can be your friend, brother, but I can't be a couple, so give up. 2. I like you, and I want to chase you because of your relationship with this girl. If this girl often takes the initiative to talk to you and help you, but you don't show a good impression on her, she may use this trick to close the distance with you, pretend to be your buddy, and then dispel your concerns about the future. Generally speaking, it depends on whether she wants to chase you or refuse you. However, I think you should be able to distinguish these two properties well. After all, I didn't know what kind of state two people were when they were in contact. You like her, and you take the initiative to show your affection for each other. If you don't get a response, call your brother, which means she doesn't intend to develop with you. If she told you this on her own initiative, and you don't have any affection for her, and you don't show any behavior of liking each other, it means that she is deliberately approaching you. Anyway, these two situations are not good; If you like her, it means it is difficult for you to further develop your relationship. But if you don't like her, but she always wants to get close to you, then you must refuse others and don't pester others.
