I printed out a copy of the phone records showing the OM number all over. Showed it to my W and set my NC boundary. I didn't wait to just stumble on her texting him. That means you actually have to look who she is texting now that is pretty hard to do. And you don't know if it's just a one off text or and ongoing thing. What's the worst that could happen with the phone records? She gets mad you're checking up on her. That doesn't even reach the "I don't care" level for me.
I know for certain its on going thing she sent 900 text messages to OM this past week.
