Is there a difference between probing boundaries and giving shit tests? Also, how can I tell if a girl is trying to "Betafy" me or "train" me to become the beta validator she tries to make everyone around her?

And lastly, how can I enforce my boundaries without having to call her out on her bullshit? Sometimes these little invasions of boundaries or "shit tests" are so subtle that it might be easy for her to flip the script if I call her out on it, making me seem overly sensitive or an ass.
