If I ever faced a situation like Anandi's, where my husband left me, finding faults in me then I would definately leave the house when he would bring the second wife.I believe there would be no point arguing with him, so I would act maturely and would try to forgive him the way Anandi did.
I may feel completely tortured, hurt or broken down by this act of his, but staying in the same house would hurt me even more, so I would move out of the house, continue with my career and settle down as much as I can.
Life may have something good stored for me as well, so I would wait for those moments to return to my life.
