Unreconcilable marriage

I'm married for 26+ months, have a Son of 14 months. Ours is a love-come arranged marriage. There have been numerous issues since the wedding day itself. She has not accepted any of the traditions in family or of a married hindu wife, like wearing mangalsutra or anything of that sort, didn't put up my surname instead has hers. Argues about everything and anything at home. Mistreats my parents, they are both senior citizens in late 60's. Doesn't cook for me, most of the time it's my mother who does it for me and my father. When asked she excuses that she can only take care of our son and not the whole family. Doesn't participate in my family functions. Disrespects my sisters when they come for visits. mostly it's through taunting. Stole money thrice and when caught her stealing once she said it's her right. She can take it and it's not stealing since I don't fulfil her needs. She talks, cries and laughs in dream and it is not just for a fraction of seconds but for minutes. Made a police call once and reported of domestic violence but didn't attend their call in return since I told her a fake call would end up in prosecuting her. Threatened me of Suicide on more than 2 occasions, drank listerine on one occasion. I recorded most of her acts, and audios but since I gave her a chance I deleted them once, but since all of this never stopped I recorded again, but this time since I didn't have a phone lock she deleted them. 1. I have 2 audios at present one where she is admitting of taking money which she feels is not stealing but what is her right. 2. Another audio where everything is being discussed by me with her family. I'm not able to take a decision because I'm worried about my Son's future. I don't want him to grow up with a single parent but at the same time I know growing in such an atmosphere it will be harder for both of us. Please suggest, regards
