With what you described, it's just air in the lines. One tiny air bubble is enough to really mess up the feel of the pedal.

When bleeding brakes, one easy way for air to get in is if the reservoir doesn't stay full. If air gets pumped just one time into the master cylinder, you have to start the whole process over from scratch again... at the farthest wheel from the cylinder until no air comes out. Honda brake reservoirs aren't very big, and it's really easy to do. The front and rear brakes are actuated individually from the master cylinder, so it's possible to get air in one and not the other, however, the proportioning valve can allow air to cross over from one to the other.

You'll get it, keep working on it.
