What does it mean when he calls me baby or babe.

We been talking since the end of may till September the 6. We started going together on the 7th and he started to call me baby and babe the next day. Now I say it back a few times but not as much as him. And he asked me why I don't say it back as much back as much. he says when he says it he means it.

Is he for real are playing games?
