Must I continue a relationship with my abusive parents?

My parents were physically and mentally abusive to me as a child. As an adult, they have never recognized what they have done to me and even try to guilt me into having a relationship with them that I do not want. I practice often, but I can’t make myself feel a forgiveness that I do not feel at this time. In the buddhist view, am I wrong if I choose not to have a relationship with them?
