<human>: Can you succinctly summarize the text in 1-3 sentences?

I noticed over the last 4 weeks or so that my wife has been very phone-centric. A lot more than usual. One day at our in-laws, as I was walking towards her I noticed she opened an 'incognito' tab on her phone.

She has been very private with her phone in the last 4 weeks. So much so that she rarely leaves it around or in the open. She tends to turn it over or take a second glance to make sure its turn upside down, whenever I am around.

So I checked my router logs, and noticed for the past 2 days that she's logged into Facebook at least 12 times.

She's had Facebook in the past, and she's been 'caught' twice before speaking sexually/sensual/emotionally to guys. One was when we were dating for about 3 years, the other was after we were married for about 3 years.
So I don't know what to think.
<bot>: Wife has FB account which she thinks I don't know about. She's been caught before talking 'sexually' to guys on FB before.
