(F22) I need to figure out if this is normal before a date (M21)

(English isn't my native language.)
I’m trying to figure out if what I'm going through is normal or if I'm just crazy. I've been texting a guy for two weeks; we live in different regions, but since we're getting along well, we decided to try going out and meeting halfway. He goes to this city often, he has friends there and for this occasion, he decided to stay for three days before our date, which is tomorrow.
As soon as he arrived, he barely texted me at all; yesterday he completely disappeared, texting me at 5 am to say he'd been out all night and was heading home. At 6 am he texted, "I'II call someone, go home, and say goodnight to you"- it was poorly written, so I'm not sure if he meant he had to make a call or if his phone was dead.
He stopped replying to my messages until 10 am, they didn't reach him, when he texted me, "just got home," "I'm going to bed, im exhausted, see you tomorrow❤️”
We've been in touch every day, and now, out of the blue, he's acting strangely, saying goodnight at 10 am as if he wants to avoid talking until tomorrow. Am I expecting too much? Is this normal before a first date?
