I've heard some people say DE isnt even a couple. So i want to know What is the Definition of a couple?

Well technically a couple are boyfriend/girlfriend, husband/wife, two people who are in a relationship ( doesnt mean they are in love) two people who are commitment one with another

so DE forn now is not a couple, Damon is in love with Elena but Elena not, they are not in a relationship so... ( I am DE fan but I dont believe that Elena is in love with Damon until now, I want see elena falls in love with Damon)

I think that is the reason

^i agree with that. except i think that DE should be counted as a couple in those categories because it's about the relationship between them rather than the definition of the word "couple". Hope that makes sense.

Well, Wikipedia defined a couple as two items of a type (Which DE is), more specifically, two members of an intimate relationship (which DE also is. I think. Didn't they kiss or something? Sorry, I don't watch the show.)

Well... Stelena isnt a couple either since they arent officially together. smd :P

I am so glad that DE is placed in those awards
