Marriage problem

I am a Permanent resident in Canada and working in IT sector. My parents found a girl on Jeevansathi site and introduced me on skype in September,2017. I went to India to meet with her in December,2017 and later my marriage was fixed for March 2018. I went to India on 28th Feb to get married on 6th March. We went to honeymoon from 9th March to 16th March to Bangkok and flew back to Canada on 18th March. My wife was to stay with my parents till 27th May, as they had a programme to come to canada since my unmarried sister is also staying in Canada. Afterwards she was to stay with her parents. During this period my parents got her new passport, aadhar card, pan card with changed surname to facilitate her immigration papers. But during this period I am finding it difficult to cope with her erratic behaviour and her insistence to break our family. I have not filed her papers so far. In case i want a seperation from her what is the way out and what protection do I need to protect my PR status and harrasement to my family. My email is [deleted]. I have given phone no of my parents who could be contacted on whatsapp.
