Can i get divorce is wife is aggressive and hostile

It's both me and my wife's second marriage. My first marriage lasted only for 4 days and my wives 3 years. In this relationship I am facing some sexual issues maybe psychological due to the problems in my first marriage. Now my current wife is causing problems and acting aggressively. She is arguing for simple reasons with me and my family. I am recording all her talks which denote that she is having a very hostile approach. I am also thinking of keeping a CCTV at my place which shows how she is behaving with me and my parents. We went for a counselling together and I was able to convince my counsellor that her hostile approach is causing me mental agony. Due to this I am falling into depression and taking medicine. My counsellor may suggest that this marriage is incompatible as it is causing so much problem to me and my health. If he gives this in writing will it be a valid document for divorce? Can I put a divorce case claiming that her mental torture is detrimental to me.
