What does it mean if a guy talks to you 4+ hours on the phone at night?

We have been talking for a few weeks and been talking on the phone for a few hours and one day we talked twice one time for an hour or so the second time that day was 4.5 hours. We talked about random things, we asked each other questions. We got to know each other more. We flirted etc.
