I dreamed my husband lied about musical tickets with a phantom colleague

husband of almost 50 years lied to me. I was very excited because I got two tickets to a musical. But they never came (that's what I thought ) My husband as I found out whent with a young and beautiful colleague. A non existing one because he is retired. So one day I said let's buy the tickets ourselves, still he didn't say anything. We went to the musical. A couple of days later we were in the car with his colleague. Just before the car ride he confessed that he took the free tickets and went with her all very last minute, I was furious. Back to the car where the lies continues, when I asked the girl if she liked the musical she got very uncomfortable, she realized that they were caught. And I also asked how long before she knew in advance...my husband was silent. It was 10 days and not last minute. He also confessed that he thought she was cute and had a beautiful body.
