Need Advice on Divorce

Hello, My marriage was for about 1 and half year and in between i came to know she has extra marital affair with person in his office who is also married. I tried many times but still its the same and after that i finally decided to leave her and don't want to start as if there is no meaning in such relationship. Firstly their family and she agreed for mutual agreement with our cast's respected members sign and after that about 2 months she denied for same and finally she filed a case for No 9 restitution of conjugal rights and shes claiming for Rs 10 lacs for Divorce. I do have proof of phone call logs as well email where she writes to the person in his office about love & etc. its now more than 1 and half year we have got separated she also demands that my family is harrasing him and after that she has left the job and claiming for ailmony as well the money from start to till date for lawyer, etc. i also do have income proof that she has never left the job till date and she is working. i have hired a lawyer my friends have suggested to file a case for Divorce and lawyer is saying to wait for some time because if we file for divorce she will file for DV case and my family can come into problem. at the time she left and we decided for mutual understanding agreement she has taken all his jewellery, clothes, etc. and now she is claiming that jewellery are with us. i am confused and scared now what to do
