Divorce

I have been married for 3 year now and was living a happy life. I am having a 2 yr old boy now. My husband is having a habit of going at night since the beggining of our marriage and he also uses very bad words and abuses me for nothing. He slowly started to stay at hotels when I asked he is saying I have earning political contacts by going at night. He is treating me so badly now a days like I am worthless. I found that he stayed with another woman in a hotel. He has booked through make my trip app and I confirmed through a friend who worked in hotel industry that my husband booked it for a woman. When asked he is saying that he went to give keys and not reveal ing anything. And when I logged into his apps, email and fb I found that a woman is chating with him and has sent baby photos and she has called him in the Morning at 4 am. And he has booked lots of rooms where 2 pple stayed in at night when we are in Chennai he is booking rooms at night to stay at Chennai. I don't see any point. But he is not accepting that he is cheating. His mother is also not asking anything and not allowing me to ask. Kindly advice how do I go about this if I want divorce i dont have job and my father is no more. There is no form of income. I am afraid to go for divorce as well please advice.
