If the Moon is slowly moving away from us, what will happen to the Earth when this actually happens?

It seems the moon is moving farther and farther away from the Earth every year. When the moon is no longer in orbit, what will happen to the Earth and the moon?

The Moon will never leave orbit. Its track widens at a rate of only a few centimeters per year, and given current rates of change, the Earth will become tidally locked with the Moon (keeping the same face constantly toward each other) long before it can to leave orbit. At that point its orbit will stop expanding, so we'll still have the Moon when the Sun expands into a red giant and engulfs us in its last days.
