The lady with two kids is really unfortunate. She has a very clever husband who tortures her inside the four walls of the house and pretends to be a nice man to the outside world.
The law cannot punish such men. At most the wife can file false case of dowry harassment and domestic violence against her husband and get him arrested. But if the husband is really daring and does fear 498A then he will happily surrender himself and spend couple of days in police custody before getting bail.
Since the smart husband knows that wife cannot prove anything in court, he will eventually get all cases quashed against him using help of a equally smart criminal lawyer.
Once the husband is acquitted, he will file counter cases against his wife and all those who supported her including the police officers who had tortured him when he was in their custody . The wife may have to pay a very high price for defending herself considering that she is economically weak. Even her children may testify against her for having their loving father arrested. Finally, the woman will end up in jail or mental asylum or might even commit suicide.
If she really does not want to have such a fate, then my advice to her would be to apply her own mind and not get misguided people with vested interests.
Firstly, she must forget about divorce and staying separately. Divorce does not exist in Hindu culture. If her husband decides to teach her a lesson, he will adamantly refuse to divorce her. Without valid grounds the wife cannot seek divorce from husband and no court will grant her a divorce.
She must understand that if her husband loves her children then he must be a good man. Probably one of her actions has hurt him so much that he detests her now. Her male tiger's ego is hurt and he is only reacting. She must talk to him, find out the reason why he is upset with her and apologize for her mistakes. A bit of ego massaging and coaxing will eventually lead the husband to forgive her. Once he is calm and relaxed, the husband may also apologize for abusing her. And the children can finally paint a picture of a happy family forever.
A saying goes like this. "God is good. God loves us. God gives us everything. But God has His own way of punishing us for our sins. But when we apologize to God, He forgives us and starts loving us again."
Now that woman should understand that "Husband is God".
And for all those who do not agree with me, please understand that families need to be united at all costs. Especially as lawyers, it is our moral duty to give correct advice to people and try to save marriages. And this case, it is obvious that the man is good. The wife is being unreasonable and selfish. Some woman do not have a mind of their own and get easily misguided by third parties especially lawyers. Please do not support a wrong cause.
