<human>: So I'm in a newish relationship. It's been about three weeks and we see each other a lot and when we don't we talk on the phone for a couple of hours.

It's the type of new relationship where things are getting serious quickly but both of us are comfortable with the speed.

BUT... we were taking on the phone tonight and he was getting really, really sleepy, but before he hung up he said "Goodnight, baby, I love you."

And I paused and waited for a few seconds and waited for him to take it back but he didn't. And since he didn't say anything about it I'm wondering if MAYBE he didn't realize he said it. 

I didn't say it back. I just told him to sleep well and said goodnight.

Can you provide a brief overview of the text?
<bot>: Should I bring it up..? What if he meant to say it and got discouraged by my lack of response?
