Divorce case

I am married for 7 years. I have a girl baby who is 4years old. My husband have thrown me out of their house and now do not even let me enter my matrimonial house to take my clothes and necessary personal use items. I have filed a contested divorce case in 2018 in jan. I am staying at my parents home for last 4 years.baby is with him.i don't want to go back to my husband as he is mentally very much abusive and not willing to be with me.so I m planning to get marry soon as I have got a good marriage proposal.But they're waiting for me to get divorced soon.My husband is also willing to give divorce but he is just dragging the case because of alimony and he doesn't want to marry anyone as he doesn't like committed married life.So my question is how can I get divorced soon ?if not possible then can I get marry while divorce case is going on?I don't want to get marry without divorce.so I want to get divorce and get marry soon(within 3 months).. please suggest me on this as soon as possible.
