Last night, while the child was sleeping, a notification came to my wife’s phone. I glanced at it, and her ex-boyfriend’s name was written there. When I picked up the phone, the messages had been deleted, but I saw who the last person she messaged was. When I asked her about it, she said she only replied out of courtesy, but why did she delete it afterwards? I didn’t want to push it too much, but I can’t make sense of it. Things were going well between us, and I don’t understand what happened all of a sudden. How should I interpret this? Should I bring it up?
