When nik was a married man, anu was so madly in love with nik and was longing to be with him every moment.Even slightest of nik's smile or a single word from him made her day.
when nik was longing for a child and was an unhappy man, she was always there to cheer him up.when nobody knows where he is, she will know where he is and goes to share his pain and help him..
Now when nik is all hers where did that anu go?now when he loves her, she doesnt trust nik anymore...
I guess nik was better off not confessing his love to anu..atleast he would have had a friend who cheered him up and shared his pain..now he neither has his friend nor love...
