It isn't used up because it performs no work. There is potential energy available in 2 massive objects that are separated by attracted to each other, but that potential energy was placed there by the energy of the big bang.
You question is a bit like asking "Why does mass not get less as it is used up" (provided all it does is just sit there). You can't use up such things, they are just properties.

Mass creates or causes gravity. Where there is no mass there is no gravity. As long as there is mass there will be gravity.
The moon has less mass than the earth and it has less gravity. Jupiter or the sun have more mass than the earth and have more gravity.

Gravity is as constant as the One who designed it. Gravity reminds us of our humanity and the faithfulness of God. Gravity will last and remain constant until God Himself fails.
Some say gravity is a scientific law. However, science did not create gravity and cannot even explain gravity, much less control it. Therefore, gravity is a divine law.

According to Newton's 3rd Law, the Earth itself experiences an equal and opposite force to that acting on the falling object, meaning that the Earth also accelerates towards the object. However, because the mass of the Earth is huge, the measurable acceleration of the Earth by this same force is negligible, when measured relative to the system's center of mass.

Gravity cannot be "used up", as it is one of the four fundamental forces, describing how all matter acts on all other matter.

Gravity is not a finite substance -- doofus.

Gravity is a perpetual dynamic process.It is never used up.It is constant......at least for now.
