Wife living separate from husband 

 S5. (1) If any person, against whom an order has been applied for or made for the maintenance of his wife, offers to maintain hiswife on condition of her living with him, and his wife refuses to do so, the court shall consider any grounds of refusal stated by such wife, and may make or enforce the order aforesaid,notwithstanding such offer, if it is satisfied that such person is living in adultery or for any other reason it is just so to do.

If the husband asks the wife to come back home and she refuses without a proper reason, the Court will refuse to make such an order for maintenance.( You have to ask your new boyfriend for the $$)
