I really don't see ANY "love" between Sid and Riddhima, NONE at all. They just show scenes and put their background music, but all they EVER do is just stare into each other's eyes have have the SAME, RUBBISH, BORING, LIMITED MEMORIES PLAY. It's NOT love.
Armaan is the ONLY true lover in DMG. No one except him HAS ever experienced love. Riddhima STILL doesn't know what love is, even after 3 years...she's just taken Armaan for granted, she USES him.
Love is sacrifice. Love is pure. Love is just given, not taken. "Love is when you shed a tear and still want him, it's when he ignores you and you still love him, it's when he loves another girl but you still smile and say I'm happy for you, when all you really do is cry." True love happens once. And you can NEVER forget that person...
I know I had made a topic earlier saying that Armaan and Riddhima will always love each other no matter what. And it doesn't matter who she chooses. But that doesn't even mean anything, anymore. SHE STILL DOESN'T EVEN KNOW THE MEANING OF LOVE. SHE HASN'T REACHED THERE YET.
