The Great Attractor is somewhere in the Vela/Norma/Centaurus region, which is pretty much opposite the Andromeda constellation. As such, the Milky Way is mostly in between Andromeda and the GA. Thus, the collision vectors of the two galaxies is mostly, "Andromeda is moving toward the GA faster".

That doesn’t sound right, if Andromeda and milky way are heading towards each other, and the great attractor is on the far side of Andromeda. Doesn’t that mean the milky way is headed toward the GA faster than andromeda is. It may be closer but the MW is narrowing that gap

You have it backwards. The Vela region is opposite Andromeda from our reference point, so we’re in between the two.

No because if the Milky Way were going faster than Andromeda they'd never collide.

Your description of opposite has to be wrong then

MW — And— GA. Milky way is moving toward Ga Faster than And

MW - GA — And Something is very wrong with this scenario

And - MW - GA. And is moving faster than MwW

And - GA - MW. Again something very wrong with-physics in tuis scenario

Which is it?

It's the third. I said right in the post that the Milky Way is between Andromeda and the Attractor because those two things are in basically opposite parts of the sky.
