Alimony

My wife forced me to leave her home since August 2019. Since then, I have tried to reconcile multiple times. However, she has consistently refused. There was no domestic violence on my part or any other forms of harassment. In fact, she did M.Com and B.Ed. after marriage. We have 2 kids from 10 years of marriage. Eldest one is a son of 9 years of age and youngest one is a daughter of 3 years. I am more or less jobless since February 2019 with a couple of odd jobs here and there. I have started a business but that is not working either. I don't have a single asset in my name. I don't own any real estate. Nor do I have a single rupee in savings. My current expenditure is being borne by my parents. My parents have sizeable assets which are self earned by them and not inherited. My question is twofold. 1) Can I file for divorce from my wife on grounds of cruelty based on desertion? 2) Basis my financial condition, if I file for divorce, can my wife claim any alimony, maintenance or child support from me, keeping in mind my parental assets? Another quick question, while we are at it. 3) Both my kids love me a lot and so do I. Keeping that in mind, can I get custody of my kids, despite my financial status?
