Hi Steve,
I think you have it right. The "resistance" is called reluctance.

If I remember correctly, the air gap prevents the core from saturating by creating a "high resistance" to the magnetic flux in the core. This limits the flux density/amp in the core material. Hence as the air gap becomes wider, the "resistance" increases, the flux decreases and so does the inductance.
