Always,
The short answer is that she was on a student visa and had to return to Sweden after a year. This was probably one important reason motivating her to ask me out first, since her stay was limited. I didn't want to get too emotionally attached as a result even though I liked her, and was therefore reluctant to get involved.
The longer answer is that she was part of a four girl 'party crew' that drank/ate/made merry together. They were best friends and coincidentally, all four were single (when I first met them) and all four were interested in 'yours truly.' I had some trouble deciding which one or all to pursue, and was reluctant to stir up jealous rivalries within the group, but the Swedish girl more or less made the decision for me. As luck would have it, I liked the Swede the most on a personal level anyway. (All were attractive, early to mid twenties btw.)
I'm now trying to rekindle the flames with a second member of the 'party crew.' We just went out a week ago and remain in regular contact. I'm certain she was interested when we first met, especially since she flatly told me of her interest ('i told party girl x i'm interested in you'), and tried to get me to take off my shirt when we went clubbing. When we went out recently, she kept rambling on about hot guys she's dated recently to try to get me jealous. This girl is stateside, so hopefully I can get this going.
If it makes the hardcore/extreme DJ's feel better, I won't be shy about letting 'party girl two' aware of my other dates, groupies, prospects, or any other hotties within my 'orbit.'
