The times he visits as Superman and what he does is a difficult battle between his self-control and his love and desire for Lois. He wants to be patient enough to let Lois get over Superman completely (he thinks that actually might happen) but he wants to be with her, talk to her, "hang out" with her so much that he gives in every once in a while, thus setting him back again. Without her knowing he's both CK and Big Blue, it's a love triangle catch 22.

I think, therefore, I get bananas.

When in doubt, think about time travel conundrums. You'll confuse yourself so you can forget what you were in doubt about.

What's the difference between ignorance, apathy, and ambivalence?
I don't know and I don't care one way or the other.
