Hi, I have recently moved to Germany with an employment visa. I have one question: I have married a widow with a 4-year-old child on sympathy grounds. The marriage took place in a temple with no witnesses, and it is not yet registered. The marriage date is October 12th, 2020. After the marriage, she started blackmailing me for money, causing distress to me and my family. My mother has fallen seriously ill three times due to the stress. To resolve this, we entered into a Memorandum of Understanding (MOU) stating that we can separate at any time without maintenance costs. Despite me paying her expenses every month, she continues to blackmail me, threatening to contact my HR if her demands are not met. If she does contact my HR, what should I do, considering the MOU that allows separation without maintenance costs?
