Oh, no! This is gut-wrenching! The scene at the beginning, waking up happily in his arms, then choosing to let it go all wrong...devastating! Clark sees what Lois is doing, how she's intentionally pushing him away, and he calls her on it. It takes a lot of strength to address a problem honestly, but he's just hurt more for doing so.
And this is all because of Lois' source, who I do not trust at all! The perils of time travel...how do you know that by changing something in the past, that you're not actually causing a negative change in the future? No good can come from Lois' lies, even if she thinks she's telling them for the right reasons.
