I honestly can't tell from just reading your point of view if she's really behaving in a disrespectful way or if you're irrationally jealous. I've dated one man who was unreasonably jealous, and I can see him writing the things that you've written. I can also imagine that maybe she really does behave in a way that just makes the two of you incompatible.
For whatever reason, TheBF doesn't get jealous over guys who pursue me, he only feels jealous over men that I admire, which seems like the way that it should work. He's unconcerned about men who want my attention, but men who I look up to do worry him just a little bit. That means his focus isn't on the attention that I receive, but on who I grant my admiration.
You seem to be abiding by some code of conduct regarding how other people will view you based upon your girlfriend's behavior, which is sometimes valid, sometimes not, just depending on the situation. The man I dated who was irrationally jealous used the same justifications for his irrational jealousy, and he was wrong because I did not treat him in a disrespectful way, he was just overly sensitive about his "reputation" and his "image", so I realize that when you make those same claims of being "disrespected" I have bad flashbacks to the fights we had, which colors my point of view on this.
I'd have to say that apart from not knowing whether or not your feelings are justified, I'd recommend that the two of you don't belong together based solely upon the language that you use to describe your feelings. They are extreme and harsh and you express little affection or respect for her. I'd say that the relationship was doomed from the first moment that you felt that "animosity" was the most appropriate word to describe your feelings.
