This type of behavior has resulted in an inquiry of long-term (up to five years at a time) police undercover work in the UK[0]. There is a short podcast series on the ways in which UC police wrecked the lives of women with whom they entered into long-term sexual relationships as part of their cover. Really unconscionable behavior by the state. The series is called Bed of Lies.
