You should definitely show her what it's like to be a lady. Take her out and make her feel like a real life Disney princess. Invite her up to the tallest and classiest building you can find, like the Space Needle if you've got one. If you don't got one, just pile up as many milk crates you can stack.
Once you're up there and checking out the stars and she's really feeling the romance, it's time to advance the plot. Much like all modern princes, she needs to hate you for a bit. The easiest way is to full on insult her. I like to keep it simple and just tell her she's a piece of shit and I hope she dies. This completes act one. She now hates you.
Now it's time for act two. She needs to see you as a man of action that saves her. Unfortunately, the only danger around is you. If you're at the Space Needle, just start muttering random threats. Nothing awful. Just things like you're gonna wait until she falls asleep and shave her head. If you're on milk crates just jump off and kick away the stairs. Now she's trapped, which cements her as Repunzel, which more importantly makes you best Disney boy Flynn Rider.
You still need to get her out of danger though so that she falls for you. This part is important. I've forgotten it once or twice and it hasn't worked out nearly as well. If you're at the crates, simply set up the steps again. If you're in the threatening to shave her head situation, tell her you were just kidding. Also, laugh so that she knows it's a joke. You'll really want to sell it, so go over the top like Tidus. This also displays your sense of humor. Women also love that.
Now it's onto the final act. I've unfortunately never finished many Disney movies because I don't have the attention span to sit and watch a movie for over an hour, except Lion King because that dude rocks. So we'll follow that one. You'll need to have your nephew around to show up and fight you for being too awesome. Let him win to show how kind you are and then all of swanky hyena type women will swarm to get a piece of you. Now you're swimming in girls.
And that's how you treat her like a lady
I don't believe in belts. There should be no ranking system for toughness.
