for the longest time I have tried to get my wife to try anal sex with me, it’s one of my top fantasies. And now I see that she fucked this random guy, but not me. She tried to tell me it just 'happened' however she didn't explain why she didn't tell him to stop.

Just a classic example of opening up the relationship with the usual ending.
