Sharing Our Innermost Thoughts

I have been with this one day. whom I absolutely adore. So it’s been a month probably. we met a couple of times, talked over long time and things did escalate. But recently he said that if I wanted us to be official then I’ll have to propose him to be my boyfriend. We both don’t want anything casual. on asking what we were till now… he’s reply was “do we have to label everything?” idk I’m confused
