Carol, I'm very glad Lois finally told Clark that she had fallen in love with him, especially since he had been wondering about the future, because this gives him an option that he had hardly considered. I was also delighted to see both of them setting aside their wishes to consider what the other would like (Lois urging Clark to do some of the things he wanted to try, even without her, and Clark refusing to do activities Lois was banned from since the pregnancy that kept her from them was as much his doing as hers). Way to go, kids!
This is just a suggestion for when you start working on rewrites, so ignore it for now. But when the time comes, you might sit down and decide on 4 to 6 ways in which Lois is a better romantic match for Clark than Lana is--sort of like you've done re their respective sizes, only emotionally, intellectually, etc. Then scatter a scene or two illustrating each way throughout the story prior to the point where L&C make love after her dad's heart attack. That will help convince your readers not only that Clark really belongs with Lois instead of Lana but that the marriage he had planned with Lana might have been in trouble even if they'd gone through with it.
Just a suggestion. Looking forward to the next parts.
