Threat & mental torture by wife

I am working in government sector. I got married in 2008 and live in Faridabad till nov'2016. I got transferred from Faridabad to Aligarh in Seo 2015 and i alone shifted at Aligarh and used to come on Sunday/ holiday at Faridabadd. Again, I got transferred from Aligarh to Kanpur in nov'2016 and we shifted along with wife to Kanpur. My wife mentaly torturing me some of examples are below : She denied having physical relation with me since 2015 as her mother instructed her for not having second baby.Sometimes she forcibly took my daughter from my arm. Sometimes she said i shall keep her away from you. Sometimes she won’t wear sindur for many days.Sometimes asking money for buying gold and forcing me to buy jewelry. She started hiding her conversation with her relatives and stopped talking in front of me.She started visiting her relatives in Delhi and even stayed night with their without informing me as i stayed at Aligarh separately.She also started calling her brother who lives in Delhi and her brother also threatened me that i have IPS officer and lawyer in my family and we will send everyone to Jail. Her cousin brother is IPS officer and uncle is lawyer. Please suggest.
