What does it mean when you aren't officially dating someone?

What does it mean when you aren't officially dating someone yet you get everything from them that dating brings? Things like someone to talk to, to go out with, someone who just checks in on you to see how your day is, someone who makes you laugh, someone who cares and puts in effort to do sweet things for you, etc... This guy told me that he's not able to be my boyfriend because he isn't where he wants to be in life right now. He feels that he can't bring something to a relationship if he doesn't even have himself together yet. He's expressed that he likes me and all that jazz and that "I make him feel safe and open and like he can get lost in me. We've been talking everyday since New Years day. We don't have a title, yet I feel like we're getting closer by the day. What does this mean?

1. Why is he continuing to talk to me and actually put in effort if he isn't ready to be a boyfriend?

2. What does it mean when you aren't officially dating yet you get all that comes along with it?

3. Is it unwise to continue to talk to someone who has stated they aren't ready to be in a relationship yet?

4. Is his reason for not wanting to date a copout?

I'm personally ok with not dating right away, but who knows if he'll be ready by time I'm ready. That's what I meant when I asked question number 3.
