Nri divorce

Hello, I live in Germany and married my current partner in may 2018. I initiated her dependent Visa and she came to germany in September 2018. After her arrival we had lits of issues and we gave deadlines to each other saying we cannot live like this for more than a year or 2 years at the maximum. We did not consummate the marriage till date. Initially it was mutual but latter she started saying she has doubts on my manliness and that I am incapable of having sex. She said it is better if we go for divorce with mutual consent. Her mother asked me to get my lawyer and they would get theirs and settle this. She left for India to attend her sister's wedding in 2019 September. Her father asked me time till December to settle his elder daughter's divorce after the younger daughter's wedding. They suddenly changed their stance that they do not want divorce. But I was firm and said this will not workout. Now her father wants 50 lakhs as compensation. My questions are: 1. Can they cancel my passport on any grounds? 2. Is it better if we file for divorce or wait for them to file first? 3. We did not have sex. Can we file for annulment?
