Guy I met from a dating app is very interested in me in person however is horrible in maintaining contact online. is he not into me?

So, I (27F) met a guy (29M) online on a dating app. The conversation was very smart and intriguing when we first matched and he instantly asked me out for coffee but I said no since we had not had a proper conversation yet. I am someone who really cannot use dating apps for a long time and had planned to delete the account the same day after I matched with a few guys (it ruins my mental peace) and hence asked only this guy to connect with me on IG.

The next day I thought he would reach out but he didn't. He had earlier told me when we matched that he finds handling online communication very difficult with work and other chores. I got very impatient one day and asked him why he doesn't really talk after sending a mere "hello"? Why is he so bad at texting or following up? He told me he finds talking behind a screen pointless and futile & often after investing a lot you realise the person is a misfit so he prefers to talk face to face.

After a lot of back and forth and stuff, I decided to give him a chance and met him on a date after an argument with him about how he didn't even care to follow up after setting the date. He said when the date is set then it means the commitment had been made and that I was not acting very mature and required patience.

Met the guy, man is he intelligent!! He speaks well, despite the argument we had a great vibe and I really liked him. He was mindful and didn't flirt with me but wanted to get to know me and held discussions on vast topics from geopolitics to religious conflicts etc. He once told me I had pretty eyes and that he saw my dimples. He paid for the date and we laughed and talked a lot, went for a walk and he dropped me home. After the date he texted me and said he hoped the date was well and that we could meet again when we are both free. He said he liked the date and liked me and i said it back to him. The problem is this guy is never on his phone. He showed me he doesn't have notifs ON for any app. He doesn't text or call me.
