If a guy talks for 2-3 hours a night on the phone with you, is he interested in you?

I've been talking to this guy for about 5 days. Of those 5 days, we have talked on the phone for 2-3 hours, three times... He has led a really remarkable life, so a lot of the conversation is me asking him questions, listening to his insane stories. I'm just wondering if this is going anywhere real. We met off of a dating site, but people don't necessarily have to date off of there. He asked for my number, he texts me throughout the day, he sends me pictures of his neighborhood, but he doesn't ask about me. He doesn't ask about the deep, personal stuff. Only I ask the probing questions. I've heard and read from multiple sources that if a man cares about you, he will want to know all about you. Also, he has seen pictures of me, I have seen pictures of him and being perfectly honest, zero humility, he is more attractive than me. Should I take all the evidence to mean he probably just isn't all that into me? And probably he's just... bored and happy to talk to someone outside of his normal life?
