If you're his wife, yes. If you're his date, his parole officer, or a genre of porn, no. Also, if he's capable of inserting curlicue brackets into his speech, you may be dating an alien, angel, or other transcendent being.

Let's break this down. First, assume you're this guy's wife. Yes, the word "wifey" is somewhat akin to "dear" or "mother" on the spectrum of terms of endearment. It's the old, reliable term of endearment, like the Toyota Corolla of love, or an old comfortable shoe.

And yeah, sure, that's not necessarily the BEST thing to call your wife, but keep in mind that it's still a term of endearment, and many men absolutely adore their old comfortable shoes. And there's a very good chance he just wasn't feeling very creative at the moment, stuck the letter "y" onto the word wife, and means nothing by it.

So most likely, there's nothing to be worried about. In fact, I'd say a good rule of thumb is if you need to rely on your husband's terms of endearment for insight on how things are going, you may need to communicate just a tad more.

Okay, now let's assume you are a parole officer, or, even less likely, a genre of adult film focused on women who appear physically similar to an average american housewife (google at your own peril). In these cases, being called "wifey" is either grounds for a savage beating or merely accurate descriptive language.

Another case solved! Now to smoke opium and play violin. Or get drunk and eat cheese cubes, whichever turns out to be most feasible.
