It it password protected? Does she take it in the bathroom with her?
Yes and Yes
That's what I figured. You have a wayward on your hands. Is an affair a deal breaker for you?
Agreed! My W never took her phone to the bathroom with her until her EA started. After it did she always took it to the bathroom. One of the most reassuring things to me is that now she never takes it to the bathroom with her. Change in bathroom behavior is one of the biggest red flags. My W went from never spending more than 5-10 minutes in the bathroom, to spending an hour in the bathroom. Now she is back to short bathroom trips again.
