Did he tell you why he wanted to break up and if so, did it make sense? There could be all sorts of reasons that this is taking place and you have not given enough info so that anyone could help.
Just a speculation that maybe he has taken the approach that if you love someone, set them free. If they love you, they will come back. It may be that he is expecting you to come back and those are the signals that you are seeing.
Either that or he has realized how much he still cares for you and regrets letting you go but is having a hard time admitting he was wrong for his actions and does not see that you might forgive him and accept him back.
There are many things but these are a couple off the top of my head. The main thing is that you both need to talk openly to find out what is really going on and also be willing to forgive, compromise and be friends all at the same time.
