I work in family practice and as you can imagine there are plenty of patients and families that rub me the wrong way and I would prefer not to see again. With these patients, I find that sometimes the second visit is not as bad. Once I build a rapport with them things improve. It can take 4-5 visits to do this. This patient's husband may be, like you said, bitter or upset over past care. Maybe once he sees good progress made with you as the clinician he will change his tune. If this is a matter of safety and you feel like your safety is at risk then that is a bit different. I have also had patients I feel uncomfortable with from a safety point of view and I will have an MA in the visit with me or someone outside the room to have my back.
