This is an issue that the show never fully addressed. I don't think Clark ever fully realised what he was putting Lois through when he ran off on her. He was so focused on how angry she would be when she found out that he didn't focus on how hurt she was by not knowing. He was so worried about his own insecurities (I needed to know that you would marry *me*) that he didn't think enough about hers. (I need you to trust me with all of you, not insist that I love the part you chose to show me.)
One of the best things about Lois and Clark's relationship as it matures is that in includes real forgiveness. They both hurt each other in real and important ways and they both forgive each other. Neither of them is perfect, but neither requires the other one to be perfect. You've captured how Lois knows that Clark is deceiving her but forgives him even *before* he's come clean. That's what Clark hasn't realized yet; that he *can* confess because he *will* be forgiven.
I'd love to see a part two of this; for Clark to find out how Lois feels and realize what a jerk he's being.
