Thanks to you both for your advice and compassion. You’re right. I don’t think he took my concerns seriously each time and probably thinks nothing will happen if he doesn’t erase it. This isn’t an isolated incident. It goes along with many other concerns / red flags that have continually popped up over the course of our short marriage. We were married very quickly so I never got a chance to get to know him.
he’s also mysteriously withdrawn 700 in cash over the course of a month. We keep a very tight budget and never use cash and keep track of every penny. It’s his account but I have access (I have my own bank account that he has access to)

I started checking his pockets and each time a large chunk was spent in one day. For example he had 140 in his pocket one day and by the next morning it was gone. He’s also “friends” with the woman he had a affair with in his first marriage years ago and still communicates with her. There are just multiple trust issues.
