It's also odd how the moon is traveling away from earth, when it's gravity is only 1.62 m/s² and ours is 9.8 m/s².
Since I took Astronomy 101 many moons ago, don't take anything I say as gospel.
Anywho, the sum of gravitational force of the interaction between Earth and Luna is the sum of both masses. Earth pulls the moon, and the moon pulls Earth.
And, because the moon is less mess, the center point around which both are orbiting is much closer to Earth than the moon.
Apparently an oceanic bulge from a mere 2 mile deep (on average) ocean is somehow pushing a moon already 240,000 miles away further into space?
Yeah, if I remember it right, the ocean is slowing the moon down, causing it to slowly depart. Not sure if I'm able to explain how that works, but that's the explanation... I think.
