Hi OP, it really depends on what these "inappropriate things" are, doesn't it? What you consider inappropriate might be crossing the line for you, but for another person it might just be normal interaction.
Difficult to judge fairly without more information.
(paying too much attention to men when I was there which was extremely humiliating and embarrassing).
Again, in what way was your partner "paying too much attention"? Her paying attention to other people shouldn't make you feel humiliated or embarrassed.
Do her actions make you feel insecure in your relationship? Do you think she needs to change her behaviour, if it's upsetting you? Is that a reasonable ask?
I think in a normal healthy relationship, each person would respect their partner's views. But then obviously it would depend on whether those views are reasonable in the first place... Not Othello-levels of insane jealousy for example.
But I think you've answered your own question - if you can't get over it, that doesn't sound as though you want to live with it does it? Either you change yourself, if you can change the way you react to her behaviour, or you change the relationship by leaving it.
