Don't want to divorce husband who send divorce notice

I got married in 2009. Me and my husband were on good terms. We also had a baby in 2011. The problem was initiated by my mother in law. She always used to be on a look out for some mistake or the other. She had a large influence on my husband. My husband soon started ignoring me because of her. He neglected our baby at large.

In 2014, my husband sent me a divorce notice. I don't want to take divorce from him. I filed restitution of conjugal rights and maintenance for my baby but my husband is not ready to give me anything. My mother in law is not ready to take care of our baby either. I am jobless now. I can't even afford a new house. What can I do?
