Is it over if he says he need some alone time to think?

I was starting to get to know someone romantically. I loved his personality and it seemed to fit well. But his communication style when he wanna know something he’s uncertain/insecure about didn’t make me feel great.. it came off strong and not empathetic. So I told him how I wanted someone who will acknowledge where I’m also coming from and be empathetic. He pretty much apologize and explained how we had a misunderstanding over texts. He also said he definitely has to work on his communication to not be so blunt. But he also understand if I no longer wanna continue. I thanked him for his honesty and how it’s great he’s honest with me. I shared how if he’s able to show me he will work on his communication approach to be a little gentle and empathetic, then I’ll feel secure and reassured to continue. I also mentioned if it’s not what he wanna do, I’ll respect and understand it. All he told me is that he will need some alone time to think about it. I haven’t heard from him in a day, not sure if that’s normal or he’s just not interested in continuing because he doesn’t wanna work on it?
