I know how to cheat and not get caught. I didn't screw up because I didn't know how to keep it hidden. I screwed up because I let my guard down and started breaking my own rules and guidelines.
I knew I was doing it, too. I had become so cocky that I didn't think I could be caught because I was just too good at flying under the radar.
In short, I was an idiot.
After a long, long time of successful prowling, I started to let my guard down. I spend too much time online in the evenings. I started staying late at work much more than was reasonable. I carried my phone with me at all times (even at home when there was no need for it to be on my person) and I scrambled whenever Hubby reached for it. I wasn't deleting naughty texts and emails anymore. I started getting sloppy about my excuses for where I would be when I went out for play time.
And the mistake that ultimately forced me to admit things to Hubby - I used a business credit card for a local hotel, and Hubby had access to the records. When he was just an hour or so away from discovering that charge, I told him. I am still convinced that it was better for him to hear it from me directly than to find out as he looked through bank records.
I am very fortunate that the fallout has not been negative - no divorce, no separation. In fact, my marriage is better now than it has been for over two decades, but it could easily have gone the other way - all because I was careless.
The Advice for Prowlers page includes link to many posts with excellent advice for Prowlers. Read it, but remember that you need to do more than read it. Knowing how to avoid being caught is worthless information unless you apply it.
Take it from an idiot who learned the hard way.
