Confused about a boy

Ugh so I met my best friend like at the beginning of this year and I'm pretty sure he likes me but I'm so confused....I have an urge to tell him that I like him but I don't want to admit even to myself. But I don't know, I'm just confused about my feelings. I'm telling myself that I don't like him but then I feel completely different on the inside most of The time. Like I love cuddling him, he makes me happy and I always smile around him and it feels like nothing matters. But then I can't imagine myself doing physical things with him unless that's just my mind in denial? I don't know you guys 😞 does this sound like I actual have feelings for this or is it just ..idk, make believe?
