Regarding caw cell

My wife is living at her maternal home since june-2018 to till date and never returned back even after putting many efforts by me and my family. Now, My wife has filed a fake complaint regarding dowry, domestic violence and making many other allegations against me and my family in caw cell in january 2019. I attended caw cell 4-5 times then they referred my matter to social counselling. I also attended the social counselling once and the I.O has failed the social counselling without informing about the date of counselling and told me that they are referring my case to mediation cell as I not attended the social counselling. My wife has also provided the list of articles which was given to me by the I.O but I have not submitted any reply of the list. I.O. told me that my wife wants to settle the matter but they always force me tell them that how much alimony i will give to her. Please help me with the issues which are as follows: 1. My wife is working and her salary is more than mine. Should I have to pay her alimony? 2. She had taken all the jwellery given to her by my parents and her parents as well. I am ready to return all her articles like furniture and other gift items given by them to me and my family will i get back the jwellery/items given by my parents to her if i do so. 3. what items can be given to my wife as stridhan and what items i can deny.
