Hardcore straight crush

Hi,I'm 18 years old, and have a biiig crush on a boy in my class. I've liked him for over 2 years, and am still waiting for myself to get over him. I even told him about 4 months ago that I have feelings for him just to be sure, because I thought it would be easier to get over him. It was extremely awkward, but at least I got a confirmation. So I'm just asking for advice from the older gays in here ;) Do you have any tips for getting over straight crushes? Appreciate any response, thanks! :))
