I'd like to see this backfire. Sooner or later she'll find out. Would her "stable" relationships with Clark and Superman still work once she realized that they're the same guy? Or what would happen if her therapy was successful and she decided to break up with one of them? Or what if she went to bed with Clark and woke up with Superman? What if he forgot who he was supposed to be the next morning?
This certainly works as a great short, but it could also be the jumping off point for a longer comedy of errors.
