I hope he dumps you. This is a major violation of trust and privacy. I’m married, have been with my partner 20 years and married for 16 and I would never ever ever do this to him. I would be furious with him if he ever did it to me. It’s personal property. Destruction of property. Never mind the trust aspect. You had absolutely no right at all. You’ve said you’ll talk to him about it but I hope you’re going to own up to everything
