exo762's reply is making my head hurt so here's a link in case you're curious as to how the tides are making the moon spiral outwards.

TL; DR - The earth's rotation drags the tidal bulge faster than the moon's orbit slowing the earth and giving more energy to the moon which moves it into a higher orbit.
