I agree, if it is really "nothing" then he should let you read his texts and hers.
A few years ago I was involved with an online spiritual group. One of the men on the group was a bit of a mentor to me. We struck up a friendship and I learned a lot from him. My friendship was totally innocent so I endeavored to bring my husband into the friendship. I let him read what I wrote and invited him to discuss the same subjects with me. Since this was a spiritual group our conversations were related to spirituality and it was pretty easy to include my husband, But by doing so he knew what was going on and we also learned from our conversations together.
When my friend sent me a postcard from Australia my husband was excited for me. (this was actually one of the most successful periods in my marriage)
