To emphasize duration of an ongoing action before a past moment, use past perfect continuous (had been + V-ing), not past perfect (had + V3)
She had been knowing him for years before they married.
She had known him for years before they married.
Stative verbs don't take continuous forms — use past perfect instead
Tip
Think of it as past-of-past-with-duration. If past perfect (had done) = 'before then', past perfect continuous (had been doing) = 'had been doing that for a while before then'. The continuous part = duration.
