How to get over a guy who doesn’t want me back?

I went out on a date with a guy from my uni last Saturday. We both knew we found the other attractive so he took initiative after a week of meeting to ask me out. We went out and I thought the date went well. It wasn’t awkward and it was nice. He even texted me saying he had a great time. But it turns out (according to his friend) that he found the date to be very platonic even though he thought it was nice too. I can agree that there wasn’t any romance between us but I just thought it was cos of the setting: we went to a cafe and then on a walk. I know I don’t have feelings for him since I barely know him but I am still insanely attracted to him and it hurts that he doesn’t want to continue seeing me. We haven’t spoken since the date but I know nothing is going to happen between us so im not waiting for anything to happen; I don’t want a guy who doesn’t want me back. But how can I move on?

This was my first date ever as well so im not sure if I did something to mess it up during the date without realising.

But yeah, any tips as to moving on would be great
