So first thing's first.....I don't care if you're Black, White, Asian, or other....if you don't work on yourself (ie your self-confidence, self-esteem, working on becoming a more rounded individual, finding that which makes you passionate about life) you won't find anyone. I mean a relationship ...
There is nothing wrong with appreciating another culture but if you lose yourself in the process that doesn't do you or the Asian culture (or your culture) any good! Be yourself and explore all things Asian that you can experience. When people meet you, they will be impressed by how open minded...
Yeah, why not just say "yes" and then tell him "no" in private?
