He has not asked my relationship status, does he want us to be friends?

He asked me to eat lunch with him several times and we just talk about school and his hobbies, etc.. he never mentioned he has a girlfriend and he didn’t ask my relationship status. He always is nice to me and offers me food; but I also nice to him back... does he just want us to be friends?
