My boyfriend got invited to a gender reveal?

He asked if I wanted to go, but he knows I would feel uncomfortable because I am trying to keep my relationship private. Thing is we work together and some co workers already know we are together. I can't help but to feel a bit jealous of him going, one because saturdays we spend together and two because there are going to be other women from work there that I know. I know some of them but we are not close and I was not invited by the person. Would you go to a gender reveal you were not invited to if you know them but are not close and were not invited?
