As to whether there was an attempt by Virginia to re-unify with WV, I answered that here a while back.

After Virginia could not re-assert its authority, there was no constituency for re-unification. Democratic politicians who'd fought for the Confederacy in the Civil War were easily able to gain control of the government after they were allowed back in, in 1872, and that government was compliant to the wishes of the developers who would swarm into the region in the later 1800's , buying up mineral and timber rights for negligible amounts of money and starting a coal and timber boom. And the great numbers of workers who were recruited for the coal mines and timber camps, moving to the WV hills, had no reason to push the state to join VA either.
