Questions: Guy's Behavior

Most guy friends I have and exes of mine where just not big into texting. All the girls I talk to are hugely into it. Your thoughts or experience?

I am not asking for preference.

I'm most definitely delulu but hopefully it's the solulu.

Sorry if its long

So there's a guy we went to high school together we were not really friends we just used to bump into each other in clubs etc. We were only saying hi but thats it. Then i finished school and we didn't see or talk to each other for a year but i sent him a happy birthday text bc we always wish each other hbd every year, both of us always say thanks but thats it. Except this year he asked a bunch of questions about me and how i like uni. Turns out he will go to the same college as me and his apartment is going to be a 5 min walk from mine. He started texting every day, asking lots of questions sending voice messages, pics about himself. Once he had to come here to my city bc of college papers and stuff and both me and him had busy schedules for that day. He wanted to meet me that day in town but during the day we just did'nt have free time for the same hour. He chose to wake up at 6 am sat on a bus for 20mins to come see me before i go to work. He was kinda awkward/nervous around me. He used to hug me back in hs in a friendly way this time he didn't do it. I wondered why. It was like a usual thing between us. After us meeting he started sending messages like im at a club but im not looking for any girl bc i have u then saying jk jk. Or putting it this way like: u know ur mine now😘🥰🥰🤗🤭😌😡😠🤗 with lots of cringey emojis like its supposed to be a joke. But he already made another plan to see me again..

So is he onto something?
