Galaxies are usually part of a Galaxy Cluster, which is held together by gravitation. The expansion of the universe is not fast enough to overcome gravitational forces, so galaxies within clusters should not be any further apart now than they were billions of years ago. Even galaxy clusters are gravitationally bound into Super Clusters. There must be a large enough scale where yes, things are spread out more than they used to be, but I have not heard of any observational evidence of that (granted I have not worked in the field for more than 10 years now).
