What is the significance of Darcy and Elizabeth's discussion of travel and the distance to Longbourne?

Mr. Darcy says that Elizabeth is attached to her family and wants to live close even though Elizabeth claims that distance to family isn't a consideration in a match,

``It is a proof of your own attachment to Hertfordshire. Any thing beyond the very neighbourhood of Longbourn, I suppose, would appear far.''

Realy I dn't know exact answer.But i little bit know about that. Elizabeth accompanies the Gardiners on a tour of the Derbyshire countryside, and their travels take them close to Darcy's manor, Pemberley. https://cochinairportcab.com/
