The GMC makes it clear in its guidance it is never appropriate for a doctor to pursue a sexual or improper emotional relationship with a current patient or someone close to them. It is also inappropriate to end a professional relationship with a patient in order to then pursue a personal relationship.

Are you allowed to date a patient?

A physician must terminate the patient-physician relationship before initiating a dating, romantic, or sexual relationship with a patient. Likewise, sexual or romantic relationships between a physician and a former patient may be unduly influenced by the previous physician-patient relationship.
