Divorce under special marriage act

Sir, my wife left me since 6th September, 2014. Already two years passed. Can I file an application under desertion ground? Besides, family of my wife suppressed my wife's illness - Endometriosis is a critical problem of Gynaecology. This disease is her past major illness which is mentioned in her case sheet of her recent treatment. Moreover, she had problems of Thyroid, bilateral spondylosis and Asthma. Can I mention those diseases in my divorce application? My wife was entitled under Government of West Bengal Health Scheme-2008. Her treatment was done under WBHS-2008 as I am an officer of W.B. Government. I submitted all the cash receipts in original for reimbursement in my office. Government of West Bengal reimbursed all the expenditure to me. But wife's relatives submitted her medical tests reports and other documents before the district Court and claimed that her widow mother and her cousin brothers spent the money for her treatment. Can anyone submit and claim in this way that they have spent all the expenditure of their sister/daughter for her treatment showing these documents? Please reply me what will do?
