My marriage has been going on for 7 years. My wife had an affair before our marriage and it continues even now. She’s left our home and is living with her boyfriend as if they’re married. We have a 4-year-old daughter. I’ve asked for a divorce, but she refuses. She’s gotten legal advice from a few lawyers. One of them called me and threatened to file a maintenance case against me. When I argued, he threatened to file a dowry harassment case against me if I don’t comply. What legal steps can I take against my wife?
