The current rate of expansion of the universe would mean that the universe keeps expanding forever. There is not enough gravity/mass in the observable universe to make it collapse into itself.
Also, dark energy is increasing the expansion rate. The most likely scenario is called Heat Death.
What you described is normally referred as Big Crunch.
