Divorce

Namaste, I have a case and would like to know solution for same. A girl got married 6 years a go, it was arrange marriage, from the 1st night onwards Boy was unable to have physical relation with Girl. For 1st year he was giving reasons like due to work related stress I am unable to make physical relation, Girl supported him and tried and took to few doctors and they in return gave medicines after the course he was able to do intercourse and by God's Grace in 3 yrs boy became father of a child, after which Boy never made physical relation with Wife, in 6 to 7 yrs they forcefully got physical that too because wife forced for same. To hide is failure he is being rude to wife, harrases daily and gives a reason of target pressure and job at Risk etc. Girls family tried lot to maintain relation of couple now the Boy has Started behaving Rude with Girls parents as he has no answer for unable to give time to wife. Boys Parents are also rude with Girl and tries and plays Blame game like stuff going missing from home and all, Girl asked to do frisking and they did same, Girl also asked to report to police on missing stuffs then boys parent got worried and refused to complain as fact was nothing went missing and also taunts by saying who are you ? You don't have any rights in this house ? You brought nothing from your parents house etc. They keeps on insulting every time they get chance. My Question is How to prove Boy as impotent as they have 1 child after efforts and medicines? Girl is not happy with the Boy as no physical satisfaction or relation between them, forget about physical no mental connect also, Boy is always busy on phone doing nothing phone is used just to hide his failure. Girl is House maker and Having 4 yrs child, how will she get justice and how will she get her daily expenses as even the boy has questioned who are you and if you don't want to stay with us you can leave this house and go to your parents place? Please revert with best possible solution asap, Girl and her family very tensed how can girls get justice in this case. Girl is very innocent and belongs to good family Urgent with steps and solution
