As usual, I agree with Canibus.
But since you asked for some verification, I'll be blunt - pre-amble: no offense intended, I'm just being clinical...

You're correct, I don't know her.
What I do know about her is that she has a boyfriend, yet she seeks validation and approval in an emotional/relational sense from an outside source (you), when she should be seeking that from either herself, or the person she claims to be in a relationship with.
What I do know about her is that she has enough of a lack of respect for other people (specifically her boyfriend - which implies commitment and that she actually cares (or thinks she does) for this person) to openly disrespect them in front of their face.
What I do know about her is that she has done the above on multiple occasions - which leads me to believe that she is not doing this because of a state of mind she's in (drunk, stoned, horny etc) but because she believes this to be an acceptable behavior to either seek validation, or punish her boyfriend.
The above are all conclusions drawn from your posts, so their either accurate, or you're being dishonest (which I doubt since you're posting here for advice). Based on the above, I feel confident to surmise that she has self confidence issues, seeks outside approval/validation for her happiness and has a general disrespect for those she's in a relationship with.
That spells damaged in my dictionary.
Your post seems a little disjointed, I'm not sure if it's because you're just in a hurry, or if you're trying to sell us/yourself a version of you that you may not be accurate. You state that you're "too sexy" and that's why girls flirt with you, but you also claim that you have "no experience" and that you only have "2 options" available to you, so I'm not sure where the truth lay. If girls can't help but flirt with you because you're sexy, then I'd think you have plenty of experience - at least in the social interaction realm, and as such, plenty of options, so this one girl wouldn't even be a blip on your radar.
I think Canibus is right about the mall, it's not empty man, if it was it would go out of business. Try a different time - Saturdays usually see a spike in business.

I'm sorry, I thought the title of this thread was "Is stealing someone's girlfriend bad?" By that title, I felt more than justified to tell you that I thought it was wrong to do so knowingly. As a bonus, I felt compelled to back up my reasoning so that it might be more helpful/clear. As to "Why is it ok to do so in bars?" I thought I was fairly clear that I bail on a girl if I find out that she has a boyfriend. I don't care if it's in a bar, in a cafe or at the circus, I'm worth a better class of woman than one who will toss aside her commitments just to hook up with a random hot stranger. I tried to imply that you might be in that same category. It's one thing to meet a woman and pick her up and then learn that she has a boyfriend (at which point I will bail anyway) it's another to knowingly pick her up in spite of that commitment.
Some don't have a problem with this, I do. Whether you plan to just sleep with someone, or make them a part of your life, her willingness to be with you and disregard her commitment says a lot about her. I choose to not allow people like that to remain in my life as relationship/sex options.
As Canibus said - and I paraphrase - You posted as if you wanted advice, but it seems what you really want is a cheerleading section to tell you to go bang her and to hell with her relationship. If that's all you want, then by all means, I'll stop offering advice, but if you want rationale and advice that might help you learn something of value, keep you from getting involved with someone who might be dysfunctional in some capacity (I'll concede that she may not be damaged and it just appears that way, but why take chances?) then I suggest you listen and put aside the fact that you might or might not be able to hook up with this woman.
I've been around/with enough women to realize that there are always more options. The fact that you see this woman as your only option is what made me "worry" about you placing so much emphasis on the success of this outcome. Do as you will, experience and time will hopefully teach you what I'm trying to explain if my words didn't offer what you needed.
