The girl sent me a message on her own initiative. I am home. Don't worry. What does this mean? I've only met her three or four times. I didn't know she would come back yesterday.

Girls can send you messages on their own initiative. Say he's home, don't worry, this girl is good to you. I like you. I wonder how you react to this girl. If you are right and he likes it, you should give him an answer at once. In case this girl is cold to you or wrong about you. You should know how to deal with this situation. Although you haven't met many times. But the impression you made on him. It must be deep. You can totally make friends. Seize the opportunity for girls to send you messages and develop feelings. Seize the opportunity and don't miss it. I think this is what you should do.
