So Lois thinks it's okay if Clark still sees Lana as long as he's discrete, huh?
Somehow I doubt Clark will agree with that. Whether or he's married for "real" or not, he's still married. And the fact that Clark realizes he'll have to break up with Lana fits with that. Besides, they have Navance's cousin (and possibly Mindy?) watching them to make a mistake. It just isn't a good idea.
Besides, Clark needs to break it off with Lana so he can start falling in love with Lois!
And speaking of being married, when is he going to tell her about his secret? Real marriage or not, they're still married. Besides, what if he floats in his sleep?
