Do guys not like me because...?

I don't look Asian? I should rephrase the question to do azn guys not like me because I don't look azn enough. I am half azn/half white but I look more tanned white than azn. I know that in Orange County alot of azn guys and girls go for white guys and girls or full azns, that's why I don't think they'd like me because I don't really look like either one. My ex was Taiwanese and moved to America 7 years ago and he's a rarity who likes all races even though his area is mainly rich, white people. Is it the luck of the draw or is there another reason azns don't like me as more than a friend (most of the time)?
