This is an issue not really well explored in some fan-fics that have Lois learning about Clark's special abilities before he goes public.
None come to my mind, but I’m betting there must be one out there.
Carol M wrote two very long fics that involve Clark telling Lois about his alien nature not only before he goes public but months into their marriage. Of course in one case it was a shotgun marriage following his impregnating her while suffering from Krptonite poisoning and in the other case they were still not even close to consummating the marriage.
Lois is right. If she had applied the right pressure, Clark / Superman would have folded easily.
CLARK:
I wouldn’t say “easily”.
CAT: Easily.
LOIS: Easily.
JIMMY (both): Easily.
PERRY: Easily.
CLARK: Fine, rub it in.
CAT: Oooh!
Let me.
LOIS: Hands off!
Well, I realize this. Even though Lois gives the reason to herself that Superman could run away, it always has seemed in my reading of this story that she really wants him to come to her willingly.
