Boy problems please please please HELP ME !?

in my school we are split into tutor groups , there's a boy in my tutor , he's in most my cles , i sit next to him in history (we have that on mondays) , but at our school we're introducing vertical tutor grouping in after our 6 weeek holidays (which start in 2 weeks) Besically in vertical tutor grouping , you're put into tutor with different years and im not in his tutor , im scared that if i dont tell him how i feel soon , i wont get another chance becasue its unlikly i'll be in any of his lessons again and i oly talk to him at school as i dont have his number or his facebook or email , im really going to miss him in my tutor - does that mean im in love ? should i tell him how i feel on monday ? , what if i get rejected ? . Thanks :)
