Counseling for parents. A counsellor.

There are a lot of problems between my parents, we have a hostile atmosphere at home and now ever since I have told them that I want to get married  to my boyfriend from another caste things have worsened. My father is threatening her that he would move back to village and keeps blaming her for my behaviour and choice. He wants me to leave my job. My father doesn't have good relationship with mother, sister and me. He hardly talk with us and now that I want to marry someone of my choice he has started thinking that he is victim. I have tried to talk with him a couple of times to make him understand that we do nit share a healthy relationship because he has refused to talk with us or involve us in any decision. Although, he agrees to work on communication at that time it really doesn't last more than a week. I need help to convince them and see a counsellor.
