Living seperately for last 6 years

Hi, I am in a situation where-in my so called wife had deserted me after living with me for 3 years at the time when my son was born, The love marriage is out of sapinda relationship. The reason, joint property ownership etc.. and at that time i was going through a bad patch in terms of career and finances. i waited for 2 years after she left and then filed a divorce case on the grounds mental harassment and also making this marriage null and void. 3 counselling happen and this kept going for 2 years due to dates issue in Mumbai family court. After 3 she came up with this malicious idea asking me to withdraw the case with no clause and then she would come and stay with kid. I wanted to stay with my kid back at any cost and do my best for his upbringing. I waited again for an year and half and now 3 months back i have again sent a legal notice asking her to come and stay with me which she has not complied to yet. She says that she is not willing to live with me but her demands are atrocious for a middle class person like me for a mutual divorce. I am tired of all this and the way working women like her in metro cities manipulate the women empowerment laws to their favor.My job is such that i am constantly travelling on the account of my company work. Anyways now i have decided to move on once and for all. I know i am in a catch22 situation, but can you ADVISE me here with my OPTIONS (look i don't have that time and bank balance being a working class person to hire a detective agency and prove her infidelity and practically its not possible , she can always deny the same), if any, or my case is to continue to be like this forever? PLEASE DO HELP ME OUT.
