Good grief, I was WAY behind in reading. Finally caught up and can't wait for next week.
I love how you haven't shied away from them having disagreements/conflicts because every relationship has them, though I'm also glad you resolved them fairly quickly.
As the saying goes, never go to bed angry.
Anyway, I agree with both Martha and Clark. He needs to tell her sooner rather than later but he needs to tell her calmly. He can't be all worked up because then she'll be more scared about his behavior and not really process what he's saying---or at least it would complicate it all I think.
Well, I really hope she handles the truth well and that Luthor is captured soon!
