Husband filed for divorce on cruelty, how can wife save the marriage

Hi, I just completed one year married life. Coz I didnt transfer the money for one month my husband beated me infront of his parents. I came to my Momhouse to take rest and also I was on medication due to miscarriage. I thought husband will take after two days but he didnt I only called him he said will go for mutual divorce I got sacred n went to his office he said let elders talk after that I took my mom n went to his house but my inlaws and husband didnt allow me to the house they told me to bring elders. but after that from past three months elders are trying to contact my husband he told them that he already filed a case in court and he is not ready to talk he will decide in court. I took police help to enter the house but my husband asked for one week time I allowed after that he came with advocate and told that he will not accept me and he filed for divorce. he cheated me. i got notice from court in that he mentioned that coz of my Immaturity behavior he faced mental torture.
