I don't think she is lieing. She is just assuming Superman understood her statements the way she now means to have them understood.
I'm sorry, did you think Lois was the only blind one in this relationship?
Lois: I am sure that Superman should have understood from our conversation on the flight back from looking at his spaceship that I was more attracted to Clark than to him. I mean I mentioned sneaking a peak at Clark's body and learning he had been shot. Of course that shows I care about Clark more than Superman, right?
