Advice Getting Over Best Friend

So in the last few months, I’ve developed an unfortunately large crush on my best friend. I confessed my feelings, and he very nicely friend zoned me. We both promised to not let it hurt our friendship, and he’s been extremely serious about making sure that it doesn’t to the point where we’ve been hanging out more than usual lately. That’s great, and I absolutely don’t want our friendship to be hurt because he really is my best friend, but it’s not exactly helping me get over him when I have to deal with the emotions that come over me every time I see his name light up my phone or hang out with him by ourselves. It also doesn’t help that in his panic to not hurt my feelings, he said that he’s not where I’m at “yet,” which i know was probably just his panic speaking but I’m having to force myself to ignore that word. It’s just a really hard situation, and I’ve never had to get over someone I’m constantly around so I’m struggling to figure out how. Anyone have advice?
