Srushy, I do agree with you. Gullu was the most imperfect protagonist and she did have those colors of grey to her character na? I mean, after Vassy's death she took many decisions that were not right (her intentions were good but the decisions ended up hurting and doing loads of damage). So all in all, it had to be her decision completely...
But then that is what was so good about this serial na...We dont have a Kesar's Gulaal...but 'Gulaal ka Kesar' concept...we dont have the ever crying heroine...all in her demure avatar to please everybody!!
She had the guts to take the wrong as well as right decision...She was so high and unattainable...yet was made to commit mistakes...she was courageous and head strong !!! not the conventional one our Gullu!!!
