This reminds me of the Reddit post on r/drugs where the cop was giving tips to dealers on how not to get caught. He said one of the most important things to do was not tell anyone you are close to about it. Although this is at a much larger scale, I don't see this advice being any less valid. And here goes this guy not only telling his girlfriend, but getting her involved. I think that he could have kept on going if he didn't bring her into it.
