So I met this girl about a week and a half ago through the girl one of my friends had picked up the previous weekend. I was talking to her for a bit, but then left to get a beer and another guy had already jumped in by the time I got back. I reacted by just talking to other girls, but making eye contact and smiling whenever we passed each other. Towards the end of the night, she walked over to me while other guy was ordering drinks. I asked if she wanted a shot, got it poured quick because I knew the bartender, and told her next round was on her. By the time the other guy got back I was already kissing her and he just stormed off with a pissed off look on his face. I ended up leaving with her, her friend and my friend and we hooked up in his living room while he was in his bedroom with his girl. I woke up, went to breakfast with her, and got the number I hadn't even bothered to get the night before.
I talked to her a few days later and she invites me to her birthday party the next weekend. She lives about an hour and half away, but I agree to make the trip. Her friend offers to drive me and I give in to her after a little debate (I wanted a way out if things didn't go well). While at her party, ALL of her friends hit on me all night, but I didn't want to push my luck so I didn't really flirt back. She eventually tracks me down and decides we're going to the bars for a bit and we ditch all of her friends.
After a while at the bars, she out of nowhere pops the question "why aren't you my boyfriend?" Which I didn't necessarily answer the best way I could, but said it was because we live too far away and I haven't known her long enough. She responded with "so?" To which I said "soooo.... is that a gyro stand? I'm starving, we should get some food" and completely dodged the question for the rest of the night and still had my way with her when we got back and in the morning.
My question is how do I get away with continuing to put off the official title for a while and not lose the girl? I kinda want the option of hitting the local scene without being disloyal or dishonest. She's making a trip out here in like two days, so timely responses would be awesome.

You barely just met, you were never looking for something serious in the first place. And beslides, no one falls in love within that short of time. Tell her to give you some time, and if it happens, it happens. but it's unwise to jump into a relationship too quikly because you'll regret not knoing the person enough or not having the right emotions.

some shit like that haha
