In the Indian Penal Code section 494, you are not allowed to get married to another if your partner is alive or until you are divorced. In your case, your wife cannot have the divorce until you say yes to it. A person is only allowed to get married if he or she has not seen or met their partner for seven years of duration. You can communicate with your wife and ask her if she would be ready to adopt a child for her happiness. Adoption is a good way to have kids if you can’t have your own. You can apply to have kids in any organised orphanage and fulfil the requirements to avoid future jargon.
