uma is in pain as mantu does not love i can surely empathize with her. but i do believe she is wrong in the choices she is making.
if uma truly loved mantu she would not have been able to bear to see his pain and would not try to keep him away for amaya, when she know amaya loves mantu too. by keeping amaya and mantu apart she is just causing him more pain.
so by that logic she loves herself more than Mantu. her own happiness is more important to her than mantus happiness.
amaya doesnt like uma but she understands her importance in mantu's life. and if amaya had to face uma situation and mantu loved uma amaya would have let him go. despite the fact that it would cause her immense pain and heartbreak. but she would not conspire to keep them apart.
even though i feel sorry for uma, i cant condone her actions.
sometime love is just not meant to be and that has to be accepted with an open and clean heart. wish the person you love all the happiness in the world. and that makes love immortal.
