Is well qualified working woman abroad earning fat salary eligible for permanant alimony

Dear Sir; I had filed for divorce citing desertion and cruelty.Period of marriage 3 yrs, period of desertion 6 years. The wife never came to the court but is seeking permanent alimony from me through an affidavit . She has denied my accusations via an affidavit. In her affidavit she has admitted that she is working abroad in the US but hasn't disclosed her income. She is a masters in engineering.However during my cross I divulged my income details of Rs 1 lakh/month while she might be earning thrice mine.she is agreeing for divorce provided I pay a hefty alimony of Rs 60 lakhs. I have done my MBA. She has filed 498a against me and my parents and also filed in her reply that I had affairs with other girls. Our reply is that she has not participated in the divorce proceedings and I have denied all her allegations in my cross.she is earning much more than me, so not entitled for permanent maintenance. Now the case is at the final argument stage. So if I can get some guidance it would be really helpful. Key questions 1) Citations where low permanent alimony provided? 2) Our reply for her demand for permanent alimony?
