Sounds like you're interested in the Philippines because you've heard the myth that Asian women are unassertive, compliant, and subservient. Don't believe it. Marriage is an equal partnership. If you can't grasp that concept get a dog.
Well ultimately there really is no reason for americans to go and seek a wife in the phillipines, if they arent better behaved and more submissive. While i disagree that all phillipine women are submissive, they better be more obediant and subserviant than american women, or americans wouldnt be with them.
