This is mainly for those that know my background

Long story short my wife just figured out I deleted some text messages. I dont think she read them. I deleted them after she had my phone for a second. I confronted her about rooting through my phone because I found other evidence she went through it after that first brief pickup. She confronted me that I deleted messages. She stormed out of the house and said she has noticed me deleting texts before, and she knows something is going on.

Advice please.

Do I try to talk to her about it? How do I find out what she knows?

UPDATE: Im almost 100% sure she read the messages before I could delete them. They were an exchange from a girl I met on Tinder in another city, whom I told I was divorced. There was nothing sexual.

I guess the cats out of the bag for me. She wont talk to me wants me to "live with my guilty conscience "
