OK, first of all i was a kind of a lurker in the forum for awhile, but i'm in need of some advice

So, i'm taking dance classes... and basically i met this girl there who seemed really cool, so i figured hey... why not. We really hit it off at first, but every time i wanted to try something more she'd back off... but still continued flirting with me.

So eventually she tells me she has a boyfriend for awhile now, but we still have really flirty and sexual interactions all the time.

Basically, i'm pretty much confused now... is she just that kind of a personality do i just move on and add another friend to my list, or do i keep pushing it a bit?

Back off from her too. If she touches you or something, brush her hand off of you. Tease her more, become more of a dick to her. Give her mixed signals so you can put her mind to work. Example: Cute creeper. Create some tension.

When you get more sexual with her next time and she starts saying, "I feel like I'm cheating, I can't do this." Just get even MORE sexual with her and be like, "I know babe.." And keep going. If she pulls away from you and stuff, just be like, "Fine, we're just friends. Haha, I like your shirt!" First you're chill with it like no problem, and second you're turning her 180 degrees to casual talk as if nothing has happened. After that, just let her open you up from then on, don't start anything with her anymore. But don't ignore her either, just treat her like another friend whose not that close to you. She's just another drop in the ocean for you.

If you can, give attention to OTHER girls in that dance class in front of her. If you can pick your dance partner, pick someone else besides her. And practice a lot, so that when you all perform, you can steal the show and get the best parts with other girls. Just have fun and be happy. Being a PUA doesn't guarantee you can get a girl within x amount of time, it guarantees opening up the door for you anytime in the future and when the time comes, it's your choice to take it or leave it.

So don't screw up now and get friend-zoned, play hard and have fun.

If you really think about it, you are SUPPOSED to become more of a dick to her by nature. Leaving culture and bs behind, if you meet a girl you like and she tells you that she has a boyfriend, it's supposed to anger you. It's supposed to make you more opposing towards her. These normal things happen with a purpose man. But we tend to do the opposite of all of that because when it comes to opposite sexes, us modern humans think more based on the conscious mind (trying to be nicer to her, etc.).
