Matrimonial Dispute

Hello, My wife has filed a complaint against me for dowry and domestic violence (which is absolutely not correct) and I had been called in CAW cell for consultation. She was 8 months pregnant when all this happened. She has put bad allegations against me and my parents who doesn't stay with us (stays at home town). Her parents wanted her delivery to be done at their place and asked for all the expenses. Now we are afraid of consequences of bringing her back as their intention are not good. My query is: 1. How much maintenance can she claim? 2. Would my regular expenses be considered while deciding the maintenance amount as I am a salaried person and have a limited income? 3. Can she enter my house forcefully. If yes, how can we avoid it until everything is sorted? 4. How can I take a divorce and what grounds? The reason why I want to go for divorce is, she never had interest in the marriage and in 9 months of marriage we never spent even a month with a good relationship. Please help me with some guidance on this issue. Thanks
