We know that Andromeda and the Milky Way are going to collide in a few billion years even though de universe is expanding and most things (cosmological) are getting farther apart.

1-How much further (in percentual terms) would the Andromeda need to be in order for it to get "expanded away" from us, instead of we falling towards one another.

2- What happens to the Dark Matter currently sitting between the two Galaxies? Will it be pushed off to the sides, ou will it get squeezed into the union of "Milkdromeda"?
