He cannot be rough towards anyone... he is hesitating, but lingering it and hiding it will cause more trouble to everyone now including Vijaya. He has to decide one way or other. Pluck the courage and tell Vijaya...so you would be freed from illegitimate affair charges and live your life anew and both ladies would finally have light about where they stand.
Nandini rejected him but he assured her of his commitments , so he has duties towards her...if he wants Vijaya, fine tell that to Nandini, else be a man and tell to Vijaya all...I know she interrupts, so give her in writing everything and TELL VIJAYA NOT TO DIVULGE ABOUT THIS LETTER ISSUE TO ANYONE INCLUDING MANSI. Vijaya may be temporaily shocked, but she wont have any problems in finding another loving, handsome husband and she is young,affluent in money and good looking.
Or else free Nandini of your claims , tell her you are a cowed and cannot stand for your love and come clean in front of the whole world.
And I hope Nandini finds someone as awesome and deeply devoted like her...who does not leave her and who is not afraid to afce world...and if it is not Akshya, it is definitely not Irfan...it is someone who soulfully and deeply loves like Nandini and fights for love, who is handsome, dashing and manly and who is liberal just befitting for Nandini.
SO AKSHYA DECIDE : YOU CANT HAVE BOTH THE LADIES. WRITE THE LETTER TO VIJAYA NOW.
