Obligated to text him everyday? I hate this generation?

I went on 2 dates with this guy I just met. I'm finding he is kinda clingy already. I didn't text him for a day and I don't text much when I do and he just said to me "Hey I’m honestly pretty confused by you I don’t really hear from you too much is everything okay?". What do I say to that? I'm not his girlfriend I barely know him it's super annoying it seems I'm obligated to text him every day... I have a life and texting is dumb, I don't wanna text with him and run out of things to say in person..
