Hello, my name is David Thomas. I was in a relationship with a man from Texas that I lived with for four months. In that time frame, he was very abusive and did certain things that I do believe directly resulted in some physical and emotional injuries that I currently have. I do not want to divulge too much information at this point. I just need to know if a verbal agreement between me and the other person, who is known to be a pathological liar, can be used in court to prove the element of duty of care. And, if it can be, would a polygraph test be in order. Thank you for your time.
