Can someone make sense of the following idea?
As the space expansion accelerates, it creates more volume/space, and since energy and matter is conserved does it mean the dark energy density is decreasing? and if the dark energy density is decreasing, why doesn't the acceleration slowing down? instead evidence suggests that universe's acceleration is constant in all directions.

You're thinking of dark energy in conventional terms. It might help to imagine that dark energy is being 'created' in empty space which causes the space around it to expand.
