I also thought that Martha's explanation was a bit too expository for my tastes. That said, I really appreciate Lois' ambivalence and I'm hoping that this will keep for a while, since I feel that what Clark has put her through (even if unintentional) warrants it.
I also want to second LoisLaneWannabe's post that there is no "right" and "wrong" way to play with your characters. The premise is rough and painful, but I think that what matters is that you carry it through and that your characters remain consistent throughout.
In response to your author's note, I don't think it matters whether we think Clark is justified or not (whether making that decision means he's pond scum). After ten years, it's like crying over spilled milk. What matters more is that he own up to the consequences of his decision and that Lois too owns up to her own feelings about the matter be it resentment, anger, etc. Only then can they begin to work towards healing.
You have our attention, now keep writing!
