Granted, this is a dream sequence - Supes' cousin Supergirl is hell-bent on finding der Man of Steel a wife (and incidentally causing untold damage to the space-time continuum and my suspension of disbelief in the process) and so visions of marital servitude are naturally enough dancing in her head.
All that aside, though: Superman is a terrible better half, just terrible. Here are some reasons:
a) Superman is a master roboticist/ virtual demigod, yet poor Mrs. Kent still apparently spends her days puttering around their horribly-decorated split-level bungalow, while her so-called better half has exciting adventures in exotic lands. She apparently has so little to do that she has become the greatest cook in all of creation, when really she should be spending her days in a Martian pleasure-palace, waited on hand and foot by automatons and subjugated supervillians.
b) This alien guy. I've read plenty of Sixties Superman comics, and I gotta say: 75-90% of the time, anyone that the Big Blue befriends turns out to have a heart full of betrayal and a secret stash of kryptonite. If he keeps bringing home every 'friend' that he makes once he's outside the ionosphere, sooner or later ol' wifey's going to get fragged. And her with nary a robot in sight to protect her...
Even assuming that Superman never accidentally brings home his new pal the Predator or something, this is a troubling little scene. Why? Three words: explosive allergic reaction. I get the impression that the Two Space Amigos have just dropped in unannounced, and Super-housefrau has pulled the latest in the endless series of meals that she cooks just to ease the bitter loneliness of her existence off of the stove and served it up. Further, I'm betting that even the Universe's Greatest Cook doesn't constantly have a series of different meals on the go, each tailored to a different alien biochemistry, and that one day an unexpected extraterrestrial dinner guest is going to end up as a thin film spattered liberally throughout the dining room. Come to think of it... maybe it's already happened, and that's why the walls are such a terrible shade of yellow.
As a final aside: at the end of the story, Superman described his ideal bride, and it turned out to be someone just like Supergirl, but not his cousin. Uk.
