I like a boy, just a few days ago to add WeChat, because in the jittery voice to recognize a former school, he took the initiative to say add friends, and then said a few words.

From the description of your problem, you can see that you are interested in this boy, there is the idea of further contact, you want to talk to him about a relationship, but in view of the behavior and demeanor of the male side makes you unsure, and from your conversation in the answer to the question, there are a few key points of his answer did not satisfy you, for example, you said that you are hungry, he if he said that I invite you to dinner, so that you are sure of the status of you in her mind, but he But he said let you rest early, of course this is also a kind of concern, but always almost what, hot love in the man and woman should not be like this. Interactive communication between you is very poor, each with their own ideas, can only say that at present this boy is not interested in you, much less want to tease you, just because of previous acquaintances, out of courtesy to add your WeChat, just take you as a common friend, if this assumption is established, then how can he be emotionally active on you as you wish.
