Gauri never loved arjun, she was just infatuated with him and since he has no interest in her it made it more challenging for her..i mean one sided love doesnt work...i dunno if that even exists...for love there has to be a connection between two people and from the way we know arjun he was never open with her...shes just a stupid girl whos not jealous because arjun didnt chose her..dumb dumb dumb..its her own fault..plus she got rajbeer as a husband who gave her divorce papers on their suhaag raat...i do feel a lil bad..maybe all she needs is a lil love and she will perk back up...lol..i mean shes been rejected by all the men in her life..LOL
I completely agree with you that gauri never loved Arjun and its her ego that is making him suffer.
But i dont agree with ur one side love theory... Dont hate me for saying this but i do have my own theories, i feel u can love one sidedly and can be ready to do anything for him/her, bevause sometimes love starts from one side and it will be successful only when reciprocated from other side.
That doesnt mean that one side love doesnt exist - but even then u will not think of hurtong the other person like gauri is doing - u r right its just her ego she is trying to satisfy now. Hope she realises it.
