Resolving my jealousy

It was a Thursday and my wife told me that we had a birthday of a friend of hers to go to. Light stuff, a livelier bar, with live music and such. I never had a problem attending social events with her, after all I love a beer. But on that specific day I was very wrapped up in work. I realized that I would not arrive in time to go, I communicated and she asked if she could go without me. He said he wasn't very into it, that he would end early, but that he couldn't not go because of their proximity. I did, of course.
