Adultery

You have not decided about the relief you are looking for through your post.

If he is leglly married to a married woman, it is basically a void marriage hence there is no question of committing bigamy.

Living with another woman without marrying the other womn is not a crime.

You  can approach court for other reliefs incuding divorce on the grounds of cruelty, maintenance and compensation towards the jewels he had taken from her.

He is still legally married to me , but he has done second marriage, I don't have solid proof rather than his own acceptance of that and they have hidden this for 2 yrs and intentionally made me go through IVF alone by guilt tripping me in name of infertility and he got baby in that relationship.

By papers , we own our house and it's an joint property, and I own 55 sov jewels and I have gave my salary for almost 9 yrs to him and he was maintaining finance , reg releif I asked him 

Handover my articles and jewels.

Handover of my share in property

Compensation for his crime 

Payment of his credit card expenses.

He refused everything and says that my earnings equals the money he spent on my treatment , basic needs and trips we went , and as far jewels he says he can only return my parents gift of 35 sovereign and he will not return the extra jewels that we bought during our course of marriage and says that he owns that , and for property he claims that it's his money and finally he has been using my PAN and doing trading (mutual fund and share) for 3 yrs by giving his mail id and phone number which I got under my control while recovering all other Bank accounts that he was operating under my name , and that holds 40lakhs and he is claiming that it's also his money.

And now myself , after giving my only source of income completely to him during all years of marriage, he also collected all rental income on the property for 5 yrs and for this property he has pledged my jewels and taken personal loan on my name and together we got private loans too , and for last 5 yrs I nearly did 5+ surgeries in name of treatments for which also I claimed whatever possible and he got them , so now after having been spent medically , physically , mentally , emotionally and gone through this adultery and affair is he right that he will own everything ? 

Is it wrong of me to earn 40k while he earns 3lakh? Though I earn 40k he took my complete salary , right now I lost my future , souce of living , etc and been staying n women's hostel and contining my job ,all I earn is give me what's mine and continue ur life , but this person is refusing to give anything and creating pressureful situation expecting I will run back to him and adjust and live.

Prima facie it is a moot court topic for debate, isn't it ?

However, if it is your personal issue, it is advisable to consult a local prudent lawyer for appreciation of such lengthy facts and professional advise.
