Yeah, my recollection is that Giovanni attempts to be blasé about David's relationship with Hella, but deep down he is incredibly jealous and possessive. This is fueled not only by his insistence that one is either gay or straight, no in-between, but also his status as "the other woman." No doubt, Giovanni is a very flawed and complex character. But while his comments are certainly misogynistic, I think his crime is bisexual erasure, not true-blue misogyny.
