Wife married without divorcing me.

Hi experts, in 2013 my wife ran away to her parents home along with kids. Then she framed me in false 498a and filed for maintenance under dv act also. In 2016 I got acquittal from 498a but in dv case court ordered interim maintenance. I didn't paid a rupee so I was jailed for 30 days twice in June 2015 and Feb 2016. Now there is outstanding amount due on me. But recently in may 2018 I came to know that my wife secretly married a guy. It was done at the house of that guy with the help of a local priest. In the name of evidence I have only images taken by phone. Please can you advice me what should I do legally ?
