Well, I have to say, as pro-Clark in this story as I am I was pretty

at him in the last two chapters.
I honestly thought when he started getting romantic with her in the bed in the previous chapter that he was half alseep. Therefore, even though it really hurt Lois, it wasn't really his fault. (because you can't control what your saying/doing when your asleep.) But even though he hadn't meant to say "Lana" he was trying to have sex or at least cuddle with her because he was mad at Lana for having sex with someone else!
Okay, I admit under the circumstances, in a way it's understandable. But he's still belittling what should be a very special relationship and turning it into a form of revenge?
And Lois did absolutely NOTHING to deserve that!
Lois also has a good reason to be upset at him since they were in Smallville. Honestly, I hadn't thought of that being the reason. But I really should have.
And Clark's still patting himself on the back for doing the "right thing" even though he's still counting on divorce. Lois is right, that's not right for the child.
I do think Lois should have cut Clark a little more slack, even though she has a right to be angry. Not just because she didn't talk to him but
"I told you something I've never told anyone else, and you've never even mentioned it. Do I repulse you that much? Does the fact that I'm an alien really revolt you?" I didn't really think that was the problem, but it made as much sense as anything else because I had no clue what else it could be.
Clark is really afraid of what people will think of him when/and if he tells them this. And since Lois hadn't talked to him since then, it makes sense that he's a little worried about that.
On that note, I remember Carol said we would find out what Lana thinks of aliens at some point. If she's not impressed with them, maybe that will help Clark realize their relationship would have never worked, anyway.
And I don't think it matters whose child it is at this point. (I admit, I'm still hoping it's not Clark's biologically.) But that doesn't really matter. Clark will be considered "Daddy" from when the child first comes out.
I do think if Clark finds out that it is his at this point, he's likely to withdraw further from Lois because he's going to feel more guilty, though.
