Why all the sexual abuse revelations?

it is because of where we are in the Scorpio part of the Aquarian Age. 

Looking at astrological charts for Prince Harry and Meghan Markle- lots of square aspects which means enormous work to overcome how different they truly are. On the surface, people think they are so much alike and will be so happy together, but the chart details don't show that. 

Harry doesn't yet seem to be dealing psychologically with his rebelliousness and this engagement seems to be another step along that journey.
