Want to file adultery along with the rape case

Dear All,

I got married a year back, was very happy initial 3-4 months, suddenly because of my drinking & smoking wife got into depression. an office colleage who was a friend to her took advantage and gave her some sedatives in cold drink and raped her in the car 4 months back, and then first threatened her of the defamed and then told that he loves her, she should seek for divorce and he will marry her as he cant see her like this. They got into a relationship for two months and then suddenly he changed his words and again threatened that he has some videos and photos of her.

Now we filed for the rape, he applied for anticipatory bail, the police and the judge have been sold out to him now, judge gave him interim thrice and now said that when the forensic will come of his laptop and phone( which he himself handed over police id not recover on time) then also police will inform him a week before arresting him. we have no proofs of 4 months back, but have messages where he has written that he spoke to his parents and they said no for the marriage. also we have the hotel bills where he took her thrice in 2months.

Should i file for adultery also, coz me and my wife both have suffered a lot because of him and we want him to be punished at any cost, pls advice.
