Can divorce be granted if one spouse is in coma

Hello, I've married for 2 1/2 years and six months into the marriage my husband had an accident and fell into a vegetative state, I was pregnant then. Now we've a child and he's been in PVS for 2 years, I've waited a decent amount of time, I don't think I can put up with my in laws abuse any longer, they are blaming my horoscope for his accident and are very hurtful towards my child and I, I've been living with my parents for the past 2 years my husband's family has deserted me, I don't see the point in legally being part of a family when they have chased me out. They are refusing divorce because they don't want me to get married again and have more children. I'm a Hindu, how can I go about getting a divorce, how long will it take if they don't consent. Every doctor will testify my spouse has no chance of recovering from the PVS he will remain that way until he dies in a few years. I am unemployed, my in laws are wealthy so will I be eligible for maintenance. Thank you.
