Someone please help me figuring out things. Do guys ask serious question for no reason?

We never met before. And we have been talking online. We start with few jokes, to which he then suddenly ask serious question. Like, what do you need in relationship, what you value in a person, all of those things. The topics has been going on for about nearly 2weeks. Then i ask him, when he asked such questions, is it because he just wanna know the person in general or he had an intentional plan in the future. To which, he ignore that question, and he ask another question..

Now im confused
