Suhani From Mumbai want legal help in Divorce / Marriage

14 years old marriage. 7 yrs kid. Husband filed for divorce on account of infedility as he found myself talking n traveling with a colleague post working hours. There was no relationship more than friendship and no physical involvement. Now this has become a point of capitalisation n he wants divorce on this ground. Earlier in 14 years we have seen 5 times lawyer but divorce has not happened. We had physical relationship between us till some months ago. Compatible issue is there but not physical mental or financial. He is earning well, supports his family.i earn fair amount to support myself n incurr sone family sudden exposure or holiday or outing. Domestic violence has been in history. In Hyderabad FIR was lodged against him it’s in records. I had to leave house at the middle of the night. My brother had witnessed that, I had to go n sleep at his colleagues place that night. While I was pregnant then also I had to spend one night outside house of his fight, my brother did not wish him on certain occasion. Unfortunately this was a love marriage.
What should be my next step to counter this petition filed by him. I want to consult with a senior lady lawyer preferably who has won such cases for women.. and can explain how I was exploited. If possible I want to meet her.
