Go with Manoj suggestion, better be safe than sorry later
have all the conversations recorded, better buy some spying devices which are available online,see below
For Example :: A pen recorded with video and audio,
with the help of devices keep collecting data and present it to a lawyer and to their parents and then start discussing about the seperation,
if you directly start your discussion for seperation you can expect hell of Women Biased cases against you and your family and your whole life will be ruined, gather sufficient proof's
without proof's if you start discussing seperation, her parents will run to police station that you have made their daughter'slife hell and file domestic violance,498A etc etc cases on you.
gather sufficient data and then only move forward.
