My spouse is being unfaithful to me with our closest friend

My spouse and I have been married for quite some time now, and we have always been completely honest with each other. We have always shared everything with each other, including our desires and fantasies. However, recently, I discovered that my spouse has been cheating on me with our closest friend. I was absolutely devastated and heartbroken. I couldn't believe that she would betray me in such a way. I decided to confront her about it, but I knew that I couldn't do it myself. So, I called my friend over and asked him to help me confront my spouse. As it turns out, my spouse had been cheating on me with my friend. But, the real surprise was when my friend revealed that he had been having sex with my spouse for quite some time. It was a shock for both of us, and we were left feeling completely betrayed.
