Notice for Divorce

Hi, I wanted to request for process and +ve and -ve which can go with me if I send notice for divorce to my wife, my case and ground of divorce is below :- We had got married 13+ years before and we have one Done of 11+ years and a daughter of 1+ year. Due to my wife's behaviour towards my old age parent's (father-76 and mother-69) i don't think we can live together and other reason is of her behaviour towards Our personal household life where most of the time we myself and our kids have to feed ourselves and she refuses to take care of home and much more interested in her job and don't want to give time to home. So almost a month before I had left my parent's home due to her such continued behaviour and decided to live a seperate life. So now she is living in my parents home and for my son's school fee and daughter's vaccination I am giving money from my savings, so that they are my responsibility and I am paying for them for all facilities but nothing to for my wife and she earns 40k+ and I am jobless for more then a year now. But looking for some of my own work so that I can survive myself and kids. Now that because of her behaviour I am away from my parents and want to live with them but not with her and want custody of my children and don't want to give any money to her, and for safety of my parents I had installed CCTV cameras at home so that I can have look at them for they being safe, because she wishes for my parents death and to ensure she does not take any such step I had installed these CCTVs and now she has damaged these CCTVs also and I am more worried about them and knowing her she may go any extreme to do whatever she wants... It's her habit to damage things to threaten others and she does it regularly. So now I am looking for some inputs from you that how can I go ahead for this for filling divorce and I should not pay anything to her and get custody of my kids too.
