How do you respond to this type of guy?

So I met this guy and he seems cool. We’ve only hung out once and text every so often. He started calling me “baby” and saying he really likes me.

I’ve never met a guy who did this so quick without fully knowing each other yet. Did any of your boyfriends do this when you guys first met?

I’m thinking he’s the hopeless romantic type.. but I’m afraid of him being the type who tells women what he thinks they want to hear lol

Not sure what’s “normal”. I don’t date much
