can I file reverse case on wife after winning the IPC 406

In response to your query,

Section 406 in The Indian Penal Code. 406. Punishment for criminal breach of trust. — Whoever commits criminal breach of trust shall be punished with imprisonment of either descripttion for a term which may extend to three years, or with fine, or with both.

As you mentioned that you have won the case against your wife therefore you may now be able to sue your wife for defamation. 

Defamation is defined in section 499 of Indian Penal Code 1860 and section 500 provides that a person committing an offense under this section is liable with simple imprisonment for a term of 2 years or fine or with both.

In very basic terms, defamation occurs when someone makes a false statement about you, causing harm to your reputation. Defamation can form the basis of a civil lawsuit, meaning you can sue the person who made the defamatory statement, and can recover compensation for your damages.
