Shall I file rcr

Hi I got married on 9 July 16 and she started living my home by 20 August Nd since then she always demanded to visit her home which is in punjab every month and it was not possible for me to take her along to punjab from Delhi every mon the but then also she went her home for a week in October. Now she is 3 months pregnant and I was out of town when her mother came to my home without I forming anyone of us in my family and took her along. She has taken everything with her. When we called her she said you have to come to my home and take me with you which I agreed upon but she said give me in writing that you will never stop me to visit my home. Reason I stopped her to visit in December was she was 2 month pregnant at that time and even doctor advised her not to visit this time and we spoke to her mother and she told I will.come in January to meet her and will take her for a month. We said that's good and now she wants me to write and give her which I denied because she can misuse that thing. She withdrawn 2000 rupees from her atm which was opened by me and I told her that if you want more money for doctor then just inform me and I will transfer. After 5 days she credit in morning and told me I don't want to keep this relation now and tell me what to do for kid. I told her are you mad what are you talking. I just disconnected phone and told her not to call me for all this. On same evening she called again and asked for money for her medicines which I denied saying that come to me and I will take care but as you told me you don't want to keep this relationship then don't ask me money and ask your mom to pay I have everything recorded in my phone. Now she is just playing with me and my family and she calls and says I am coming today tomorw but nobody is approaching my home Now please advise me what to do Shall I file rcr? I don't want divorce and need her back with my child. It's from both of us that we didn't had any fight or quarrels .
