I wont say kabir loves or loved her .....but he was in relationship with her for 3 yrs..the time he spent with her he was showered with love,care,affection,the small moment shuch as gifts,wishes,suprises,care when sick or hurt etc..would have been there....he was never loved and care from anyone(not even Anupriya as she was in mansion)..so basically the only person in his life who kept him before themself was Riddhima her love was limitless and selfless for him...which he never realised in his quest of revenge
Now today when he his all alone...he realises what he lost(Vansh has a role in it..making him realise it)...he realises the reason of Vansh happiness and peace even after all the chaos is Riddhima ...which he had once..
He is an injured wolf with nothing to lose ....having Riddhima back(acc to him) would not give him the care but the best revenge and destruction of Vansh as she has become his world..
It was a random thought which crossed my mind so thought to share with u...What do u think abt it?
