Alright, still the same minor problem, I hope however you'll give it some time. The same guy in my school who's been on/off with me giving me such a pain and so much confusion I guess is trying to come back to me?

I was walking with a friend (the same friend he left me for, as in started flirting with instead of me) and he was hanging out with a group of his friends, we were listening to music and so was he. While I was listening he called out to me and ran towards me and was like you have to hear this song it is so good for you. The song was about a girl walking near the guy not giving him attention and him being so into her and wanting her to look at him. And that was kinda the situation happening between us.
My friend left us to talk with another one of my friends. When we were alone I asked about a problem he told me about a week earlier, he had opened up his heart to me and no one else about a problem he was facing, the story didnt finish, he promised to finish it but never did. We got interrupted and so later that same day I told him that I was interested to know the rest but I didnt want to annoy him by telling him to finish it so whenever he found the right time he should come and tell me the rest and he was like yeah I really want to and need to tell you the rest. So today after one week I asked him about it and he was like alot of things have happened since then. Then he was like I've got to take you and talk to you and tell you what happened. Then his friends called him and we seperated.

He's been telling me he wants to take me and talk to me (about other things) for a long time but never did. I was wondering why he tells me he will and doesnt... is he playing games again? I dont want to fall for him, I just want to understand him! Why would he start a story and have 1 week of chances to finish it but never did? I dont think I did anything wrong because everyone tells me Im a good listener and really help people. Please help?? What do I do???
P.S What does he mean about the song? He lets me hear many songs on his mobile, am I over analyzing things?
