I think Im in love with my best friend

I (20f) think im in love with my best friend (20m). i had a dream about him, i feel like jealous almost when girls go up to him. i dont even know when this started but its been a few weeks now and i dont know what to do. like we were out and were both drunk but i was wearing heels and kept stumbling so he put his arm around my waist to hold me up and i dont even know how i held it together the butterflies were going crazy. we were just talking and i said something stupid and he laughed said “you know what i actually fucking love you” hes told me he loves me a million times ive told him i love him a million times and i had to remind myself of that because i cant stop thinking about him like that. im just scared if i say anything and he doesnt feel the same its going to be so awkward and like how do you even tell your best friend youre in love with him? do i not and just hope it goes away?
