Do you think he likes me?

I get to know this Australian guy from a dating website and had been chatting for weeks. He never say that he likes me but often he will make long distance call to me before he sleeps to chat with me. He will do silly things or imitate me to make me laugh when i'm upset. When he made me upset, I will not tell him or show him, but next day he will asked if I was angry with him? But the same time, he is still logging on to the dating website. I did asked him why he still logging on to the website, he just say that he is not stopping me to know more friends. I am puzzled by his actions and is upset at the same time. I do not want to get hurt again.
