If you PROACTIVELY offer up some sort of reason to your wife, it's only going to appear manipulative -- like a tactic. So, no.
And even if SHE brings it up ("Why are you so short with me lately?"), if you say something like some people suggest, like "It hurts too much to interact with you too much" (or something similar), then you appear WEAK. Ehhh . . . not attractive.
My advice would be (and this is ONLY if your wife points it out), to say something like "Sorry, just been really busy and actually in an okay place right now. But I didn't mean to sound rude at all, and I'm sorry if you took it that way."
My mentor thru my sitch had a few mantras, and one of them was "You can't teach a wayward." We always think -- esp. us guys, who are natural "fixers" -- that if we say something JUST the right way, that we'll somehow get thru to them or something. Doesn't work.
