It's all bullshit. If a girl likes you enough, she'll drive to your house that's an hour or two away for a quick booty call. She'll ignore your ripped clothes or how smelly you are. There are plenty of stories of rich husbands getting cheated on for literal homeless addicts and bums. How you figure out if a girl genuinely likes you, is how many hoops and bullshit tests she puts up to block you. The less, the better.
