I certainly know of a case in the 70's where a PMRAFNS Flt.Lt was happily involved with a J/T until authority got involved.
She was given the ultimatum of commission vs marriage and, being the lady she is, told authority what to do with the commission.
The unfortunate irony to this was, some years and one divorce later, said J/T got his commission.
There's also another little bit of arcane management from this era.
If an airman separated from his wife, his wife being a civilian, then authority took a very dim view of another airman subsequently becoming involved with the lady because she was deemed to be, in that equally arcane parlance, still "the wife of ". ...irrespective of the fact she was a civilian.
People didn't even have to be on the same station or locality for this draconian philosophy to be imposed.
