It's not that space ceases to expand, it's that gravity is stronger than the expansion. The mass of our galaxy is enough to prevent (currently) our galaxy from expanding along with space. For an intergalactic example, in the local group, gravity is strong enough to cause M31 and our galaxy to approch each other.
