Well you broke NC, and that's ok. We all have been there. But just because he was nice and he talked to you, doesn't mean anything. You can't read into his chat, and if you continue to contact him, he will eventually ignore you and you will be more frustrated. Take the conversation, and accept he was nice, and wasn't mean, and leave it alone. He will begin to hurt you with words, because your refusing to get the message, that he doesn't want to be in a relationship with you. Even if he decided to come over, it will be for sex, and then you will be in an emotionally rollercoaster and wouldn't know how to get off that horrible ride. If he wanted to be with you, he would contact you and tell you. By him not
Sorry, It means nothing.
Thats the problem with breaking NC.
