I am so confused !!!!!?

I'm 12 . I usually tell my friends that love is what we do in the future not now. There's a guy i know also 12 in a different cl who i think is cute. When i think abt him my heart would skip but when i see him my heart doest feel anything just want him to talk to me. When he sees me he would smile or do some funny/cute actions to make me laugh.I never noticed before cause i was with my friends but they told me he was doing it to me so i dun noe.... He also asked my number.Do i like him or admire him And does he like me or just ...??
