In love with a close friend - tell/don't tell?

[Bad Hamster]

Hi my little kittens ~
Alright, I've got a question for you guys:
Have you ever been in love with a close friend, and did you tell him/her?
Or, if you haven't: would you tell him/her? Even if it could ruin your friendship?

Friendzone = Friendzone. If they consider you as a close friend it won't be more. There is no way getting out of that zone, so don't tell.
