Why not spin it towards getting some more attn from the SO unless of course your married to an ice cube or worse.
"Honey, Do you remember when...BBBJ, Greek, and wore French maids outfits...? Worked for me and it's worked for others.
Oh and take the computer into someone and get it sterilized. Learn how to boot off of external drive and password protect that drive. (there are some Dell drives that even Dell can't get to without board replacement but that's not that hard to do) Never use (boot from) the operating system on the computer to play ever again.
Why do I say that? You have to be proactive, get all the data off the computer, tell your wife it caught a virus. Do something proactive before she tells her friends who know enough about computers (or who have hubbies that do) and divorces who load your computer up after you leave for work o(r just clone the hard drive) giving you only just enough rope and a chair to have to explain everything.
There are programs to take your keystrokes to the cloud, have them analyzed, and then emailed back to her non existent email account. Put TOR browser on that drive and then use an anonymous email client.. Ask the guy who gives your tainted data the dip, He will show you. I am currently in IL and my computer thinks it is in Nashville. My mac address changes every hour.
One of my ex's teacher friends was married to a PI who, without my knowledge, was best friends with my atty. I got a heads up thanks to a lawyer who would rather have a $$ bottle of Irish vs 10K in fees. I saw the money was missing from her slush fund and I was still married so I was off to the store for another bottle for the PI. That was 10+ years ago. Women are smarter now when it comes to divorce as all their friends have been there and learned lessons they are willing to teach. While you're at it have the guy look for dirt on the wifey. Never Know!
Maybe we should have a tech sticky about this as there are lots of IT guys around who do this for more than fun. Really something that looks like a flash drive can give someone remote access to everything without a trace.
Could this man be your downfall? LOL
