Thundering dolt doesn't begin to describe it. Clark needs to actually listen to his wife. How many times did she say that she wanted to go away with him to be with him? To spend time with him? To focus on their relationship?

I don't doubt that Lois feels the aching absence that the childlessness of their marriage has created. But it certainly seems like Clark feels it more and is transferring those feelings to Lois. He is hellbent on destroying their relationship despite the fact that she's making very clear at this point that she wants to *fight* for their relationship.
