Alimony if cruelty proved

Learned Members, I know that no final Alimony is to be paid if Adultery is proved of wife. However Plz specify if only cruelty of wife is proved, then also Nil Alimony has to be given to wife in Divorce case or I have to pay as per my living standard. There can be thousand types of Cruelty, so if we prove any ,one type will I have to pay Nil final Alimony ?
