Why wouldn't they be interested?
I recently moved to another city and got in a group of friends(15-20), most of them girls, though. I'm going out with them quite often, having fun, no stress, dancing with many of the girls in our group, complimenting them, hoping that at some point some of them will react somehow. They like me around them, I know that because when for some reason I'm missing a party they'd call me to see what's going on. I know that many of my potential targets are single and I also overheard that many of them find me attractive. I'm not trying anything concrete besides just short flirts with some of them sometimes, I'm just being nice, helpful etc. (one of them even told me that I'm being too nice sometimes and that guys shouldn't be like that).
Anyway, despite all these, none of them seems interested. Or is it just me not noticing? What is actually going on? Thanks!
