Boyfriend online until 1am?

So my ldr boyfriend is usually online with me until about 12am-1am and then goes to bed but when I say goodnight earlier he is still online until those times and what possibly could someone in a relationship want online at that time that's decent? I wanna believe that it isn't anything and I'm just over thinking it , any ideas or might there be more to it?
