My boyfriends snapchat score goes up by at least 100 a day when we aren’t together - is he cheating?

Every time I go from my boyfriend, his snapchat score increases by like at least 100 points a day. This means that he is sending and receiving that volume of snaps. This can’t be to his boys so it must be a ton of girls? I also don’t know how to bring this up but I am majorly bothered?
