Wife abusing me for her endless expectations

Hi, I have made every possible attempt to meet wife's needs, purchased site one on her name, and one more registered with both of our names, constructing house too. We both are working, it's been 7.5 years of marriage n have 2 kids. I never asked her salary for my home expenditures, school fees, travels and not even for hospital expenses. Together contributed for site purchase, home loan EMI paid by me. I never forced her to pay for any item even milk packet. I do take care of her expenses. With all that I am going through daily torture of her abuses, I tried a lot to show her to doctor for her behaviour, she refuses n make big issues. I consulted near ones many times n they tried to convince, but wife never turned up with positive attitude. Her mother n they think they can live without me, I stopped myself for not going too far divorce n tried to give all possible options to live together. Even after fights police advised try to treat her or leave her in their home for few months. She refused to do that.. The core problem is wife wants accountability of my salary, n expenses. I refused many times, I am sure what I am doing it is for my family so why should I do this every month. I pay nearly 1 lakh as EMIs I never took even 100rs from her for that payment. I am very attached to my kids. I am helpless unable decide, what should I do now. Please advise me Thank you Vijay
