i actually did that. fight fire with fire.
whenever he goes out for drink i ask him where, he'll just say out or town. but everytime he ask me, i'll say exactly where and with whom. so to spite him, when i go out and he ask where i'll just say out. and i purposely go out every alternate day and when he ask i keep say out. and purposely dress up also although it's just taking a walk around the estate or a bus ride to nearby places. but i tell my mother in law. so she knows where i am.
