I hate to be the one to break this to you, dude, but as a general rule, women don’t pretend to virulently hate men they’re secretly in love with as some sort of elaborate courtship ritual. That’s a trope we made up to justify why the male protagonist always gets the girl in the end even when it’s starkly at odds with prior characterisation. In real life, if she acts like she thinks you’re a creep, it’s because she thinks you’re a creep!
