This is totally worth a read -
Asian women are not "too tempting" for your husband or boyfriend.
Are there women in Asia who will try to get into your partner's pants, even knowing he's attached? Sure, but that's true around the world. There are also women in America, Europe, Burkina Faso or wherever who will try to get into your husband's pants knowing he's attached. There are also men who will try to get into yours, knowing you are attached. That has nothing to do with being Asian, either racially or culturally.
Are there Western men who seem like stand-up guys, who go to Asia and suddenly turn into philanderers with a fetish?
...but the problem is not the women. It's him.
I don't know where this tendency to blame other women when a man turns out to be a prick came from, but I sure wish it'd stop. I've seen it back home, where race or culture aren't blamed along with the Other Woman, and I've seen it in Asia, where they are. I do realize that plenty of people also lay blame on the cheating man, but so often that's either minimized or, before any cheating has taken place, fear of infidelity is placed on the shoulders of "those women" rather than the truth: either you trust the man you're with, or you don't. And if you don't, then don't go blaming "those women".
