ELI5: How will the upcoming Russia/US space station remain in lunar orbit without being captured by Earth's gravity?

It's all in the title.  How do you keep an object (like a space station) orbitting the moon without that object being captured, and pulled in, by Earth's gravity without using an unreasonable amount of fuel?  If Earth's gravity is strong enough to hold the moon in its orbit (less the small distance away from the Earth it moves each year) does it not stand to reason that the Earth's gravity will hold something much, much smaller?

The force of gravity is inversely proportional to the distance squared between the two things. By having something much closer to the moon than the Earth, the moon will have a greater pull in spite of being less massive. Much like why satellites can orbit the Earth in spite of the sun being significantly more massive.
