Why does a boy who says he likes me always send me messages instead of calling me?

That man should be more reserved, for fear of making you angry by saying something wrong on the phone, so he chose to send a text message, which can express himself well. To tell the truth, I am also such a person who obviously likes each other but is afraid to talk to her on the phone.

So you'd better wait and give him a "signal" to let her know that you have him in your heart and that he will act soon.
