Husband wants divorce as he saw messages of wife and her friend where wife says she loves him

Hello there, i got married 9 months back and found out that my wife is loving some one else through whatsapp messages of her with other person after 6 month of marriage. when i confessed saying i saw those messages she agreed to that she made mistake and when i asked for divorce she and her parents are adamant and not agreeing for divorce and as we are only 3 me my mother and father, 9 of there family members came to our house and tried to assault us and threaten to accept her back upon which we have filed a case and same day night we got call from police station as my father in law is in Police department they tried to call and threaten us for which i have filed case on him with his higher officer but again the investigation went to his district where all the police were supporting him and indirectly threatened us. and they filed a case where the FIR dint happen but in the name of counseling we were called to police station and forced us to take her back even though i mention i dont want to. now they are acting as if nothing has happened even though i have all the proof and adamant on not agreeing for mutual divorce. please suggest on how to get this over with as i am feeling suffocated as every one mention about her life and feels like a men's life dosent matter for any one and only way out of this is by ending my life.
