What should I do about my husband's refusal to support?

Hello sir, I am Hindu, married for 2 years, and have a 5-month-old baby girl. I am currently nursing my baby and working in a government job, with a 1.5-hour commute from my in-laws. My husband works at the same place, and we earn equally. He promised to shift closer to my office but is now stubborn about it. He is asking me to buy a flat, claiming it will secure my money, and is not allowing me to send any financial support to my dad. My dad is working but has a home loan, and my sister and her 5-year-old child are dependent on him for various reasons. What should I do? Should I consider divorce? He will not agree to a mutual divorce. Can I win the custody of my child with WhatsApp chat as evidence? What if the case is dismissed? How long does a contested divorce typically take?
