One night change (Cedric Diggory, Mattheo riddles) Love Triangle

you were going back to Hogwarts it was your fourth year. you have a boyfriend who you love very much. But became very distant after he starts to like someone else and you did too. You met a boy that gave you butterflies in your stomach all the time when you saw him. Every time he sees you he gets butterflies in his stomach. I met another boy and all I know is that I have to pick.
( he didn't die)
I'm sorry I just have to change a little bit but now you are in a triangle love. to make more drama
(sorry not sorry)
