Anniversary and he wants to hang out with friends?

Okay so we’ve been together for 5 years this weekend coming up. He knows our anniversary is coming up. We always hang out with friends on weekends so I asked him all I want is to not hang out with friends that specific weekend. And now he has planned us a weekend with our friends who have recently moved. He said we’d leave Saturday be back Monday. Saturday to celebrate his friends son graduation that’s day spend the night with them and then “wherever I wanted”. We invited them to our son’s graduation party and they didn’t show but I also asked him we could visit them another weekend but not our anniversary weekend but he already has made plans with his friends. Am I wrong? I just feel like shit if I complain about it but I had already told him multiple times I just wanted “us” time?
