Also, we have a shared cell phone account in her name. We don't get detailed billing, but I can look up call records online. And I have checked all the way back to October and don't see anything unusual.
Texts are a different though. I can only see the number of texts delivered. So what I do is keep an count of the number of texts and compare that with the texts she sends me. The count may be off by 1 or 2 a week. And when the number are way off (more than say, 5), she'll usually say something like "I got a text from my mom today". Could she be lying? Possibly. But she doesn't know that I am checking. So it doesn't make sense.
