Marriage took place in the month of december 2013, during honeymoon she disclosed that she had an affair with a persona who is already married and having two children. My family tried to convience her to forget about past and live peacefully. However, she didn't wish to do the same and herself had given an statement in mahila thana as well as an affidavit , after that she had left my house and presently residing with him.After this her family had lodged a complain against her boyfriend for kidnaping and after that she had given a statement under sec 164 of IPC where she had narrated that she had already married with her boy friend in the year 2007 in a temple and her parents forced him for marriage. She also told that my earlier marriage was not disclosed to him ( my first wife died during pregency issueless) whereas the same was already informed to her before marriage and also she herself purchased the goods for the marriage, even before marriage we had gone to movie and resturant. I had booked her train ticket also for her travel through my account. I had filled a case for nullity of marriage at my native place whereas she had also filled a case at her native place under sec 11,sec 12 (c), sec 10 (3). Please guide what action i should take, whether her marriage with a married person is valid, at the time of her so called earlier marriage she was 18 yrs 9 month old.
