Passionate kiss?

What do passionate kisses mean? Would a guy give you such kiss if he didn't like you?

We walked home from birthday party together and when we got to the crossroad to say goodbye, he came closer and grabbed my head and kissed me passionately.. It's not the first time he did that, but before this he told me that we should end casual relationship and now he kissed me again, I just couldn't resist him, it was a great kiss so far.. So, what did he mean by that?
