I totally agree with Mr. Tonja, senior advocate. Beware of the advises given by the people, who are biased and are fighting legal cases against their own wives.
If both husband and wife mutually agree for economic, social, cultural, health or any other valid reason to live separately, then it is O.K. Even though it is not defined in the Constitution, wife has got a fundamental right to stay with husband and vice-versa. A husband without having valid legal separation decree granted by the competent court cannot refuse his wife to stay with him on some pretext. In your querry, you did not mention that it is a visa problem and so, I am not dealing with it.
