Procedure to file for divorce after 5 moths of marriage.

Hi I want to separate from my wife after 5 months of my marriage. They had a meeting yesterday with us and saying that we have to give money to her for stay (purchase or rent) and monthly expenses of her including her son education and all till she get next marriage. They are excepting her behavior mistakes and compromising on above expenses till her next marry. This is more about out of court settlement thing in front of my one of family member who has Law knowledge. She has 70 lacs rupee in her account (past husband policy money). My question is that in such case maintenance or alimony is applicable if she has such money in her account??????? I had a second marriage on 2nd July, 2017 after the death of my first wife due to cardiac arrest on 3rd March, 2017. I have 7 year old son. I did arrange marriage with a girl having 3 year old child whose husband suicide. I was misguided by girl and her family about her nature. Now her behavior is not at all tolerable to me and my son.
