Why do you always take the initiative to send me a text message and then don't reply?

I guess there is something wrong with your answer.

If a girl really likes you, she is so active to you. If your answer is not what she wants, she will be a little disappointed and lost.

If you like her too, show it. If you don't like others, give a hint, lest you break the girl's heart after a long time and even have no friends.
