Try putting a divider (preferably an opaque divider) a after they lay eggs again, leave the female with the eggs on one side and the rest of your fish on the other side, see if they hatch that way.
You don't need to leave the male especially not if he's harassing her when the eggs go missing. I would fear for her life if the eggs get eaten again and they're stuck together in one side of the tank where she can't escape.
