i need advice.

ok so i have a crush on a girl but i also have one on a boy? i’m not sure for the boy one but i had a big huge crush on the girl and i don’t know what i can do

for example the boy is my exs bestfriend
and the girl crush is one of my classmates

i don’t know what i should do because all the friends already know i have a crush on a girl

but the boy already told me that he knows i like him but i liked him after he said that i never had feelings for him only mutuals
