I have been married for 3 years and have a 9 month old child out of this marriage. My mother passed away just one month after my marriage. My wife has been abusive and physically beating me and father physically . Not giving him food, throwing away his belongings, not allowing him to use house things ( this house belongs to my father not me). She threw hot tea on my father twice. On an extreme, she once tried to set fire on my father's bed while he was sleeping. I recorded all this and then she doused it off. He was under the influence of his medication and kept sleeping. We called the police and filed the complaint . I tried to make her understand but with no avail.
