Jealousy?

So there’s this girl I work with and my husband works at the same day place this girl has a nice big booty and better than mines, we were talking about her because we think she quit her job and my husband didn’t know her name and we were both high atm so I asked the one with the big booty and he started smiling and was like I think and I was like you act like you don’t look at them ladies asses and he just kept smiling and denying it and I kept asking but he never said yes he was like nah and was smiling. Am I just overly jealous or is it not okay for them to know instantly she has big ass?
