So she was all over him, how do you know she wasn't just playing around? Kinda like girls that take photos with guys at parties but don't really date or screw those guys.
With that said overtime I have met cute (keyword) White girls with Indian guys. Two months ago my friends and I were eating at a restaurant together. As we are sitting down and chatting this woman who looks a lot like SE Cupp (the glasses, the face, and all) wearing a white top and yoga pants comes over to talk to my friends. They're talking and they introduce me to her, we are all chatting and she says her boyfriend is going to be arriving in a few minutes. Well he does arrive and much to my surprise it is an Indian guy but not a nerd by any means. MLB cap backwards, nice shirt, and dude looked like he had been hitting the gym. No accent or anything. Cool guy to chill with and they had been dating for two years.
I have seen Indian guys like the one I met that day date above average looking White girls who fit the educated or hipster niche. It isn't common though, I have known more Indian men with Asian, Black, and Hispanic girlfriends.
