When I moved in with my husband, who was then my bf, I admit I snooped through his stuff. I found a box with love letters and photos from gf's. I found items left by old gf's. I made sure I put everything back exactly how I found it and didn't mention that I snooped. I didn't find anything terrible. I'm not sure what I was looking for. I was just curious about who I was committing to.

I confessed it to him later on. He didn't mind at all.

I think you have had many concerns about this woman and you are ready to put on the brakes anyway. Her sticking to her cover up story, which is obviously the edited version of the truth does show a lack of trust for you. I agree with the above poster. What's the big awful deal that she once had a spicy exchange? It's not the worst thing. Maybe you are acting like it is too terrible and that is why she is sticking to the innocent story.
