What do I represent when girls send messages on their own initiative?

If a girl sends you a message on her own initiative, it means that she thinks you are a trustworthy friend and trustworthy. She may think of you when she is bored and want to chat with you. Maybe because this girl likes you, she often takes the initiative to chat with you, hoping you can notice what she means. But no matter what the situation is, it means that she doesn't hate you and doesn't exclude you. But according to the information you said, because there is too little information, it is impossible to judge whether she really likes you. Need to judge more through other aspects.
