Do you think he is interested?

So, I went out on a date with a guy a few months ago. He called me a week or so after the date.We both just got out of a serious relationship just weeks before we went out. We chatted online for awhile but not so often. Then a few weeks ago he just shows up at my house and wants to go for a ride. So I do, he gives me a good night kiss and goes on.......... And now he IMs me everyday. And we chat,But Im not sure if he is interested.I always thought that if I guy was interested in you he WOULD ask you out. Because I know when I want something I go for it. What do you all think? Thanks............
