Girls, My crush leaves me on delivered, but when we talk, we don't talk like friends. Does he like me back?

My crush often leaves me on delivered for about a week before he replys my messages. He says it's because he's busy. But when we talk, he always tells me how special I am and how glad he is to talk to he. Is he really too busy to reply the messages? Or is he just simply not interested, and says some sweet words only to confuse me?
