My wife continued to text and message her ex boyfriend after we were married. I’m not really sure how long that the two of them were secretly messaging each other. I’m estimating one year based on some late night drunken stoops where she would make a mistake and either mention his name or drunk text him in front of me. I gave up paying attention.
No need to snoop at her phone. She would literally drunk text him while I was sitting next to her.
I have no proof that anything else occurred in terms of a physical affair, but of course have suspicions.
