I NEVER, to this day, have told my husband how I know I what I knew. I just told him I know you did this and that, giving him just enough to know that I knew but not enough to give away my resources. When he asked how I knew, I told him that was none of his business. It did the trick and nipped it in the bud without giving away my source.
I told my husband I am watching EVERYTHING.
Haha. Good to know. That's how I will approach it too, should the need arise.
It is also a good idea to have back up spy resources, such as spyware on his phone. That will give you text messages, websites visited and some have a built in GPS. You don't want to have all your eggs in one basket in case your spouse goes further underground.
Hmm. He doesn't have a smart phone. As a matter of fact, it's about the
dumbest phone out there. It doesn't have any bells or whistles, as he loathes the phone as it is, and technology is something he has absolutely no interest in. I do check his phone calls on it (he has yet to figure out how to erase them), and our cell phone bill, since I am the one that sees it, and he has no unusual calls at all -- just me, the kids, and his relatives.
He has no texting or web browsing on it at all. The phone doesn't even support a web browser and he doesn't have a texting plan. We get charged per text if he sends or receives one, and we have never had a charge on our bill yet, except once, a long time ago, which was a test text that I sent to myself when I first got him the phone. I have been trying to get him to "get with it" and get an iPad and SmartPhone, but he wants nothing to do with either (I have both). So glad now that he isn't interested. I will DEFINITELY not be encouraging it in the future. The only reason he even carries the phone is because I make him, so I can get a hold of him in an emergency. I think he only uses about 30-60 minutes a month in calls on it, most of the time, and they are always with me, it seems. I don't think he is aware of prepaid throw away phones, although he might be. I did check his car and briefcase for one and found nothing. I know for a fact that he wouldn't get a phone to do all the web browsing, texting, etc. with. He's too cheap and wouldn't be able to figure it out on his own anyway...LOL.
I'm curious, as I see you are 9 years recovered. Do you still check up on your FWW? I am thinking this is something I will have to do long term, if only for peace of mind for myself, even when it gets boring and what not.
