They are very good to their men.
The average Filipino, Khmer and Viet men got nothing to do (career), so they marry and became fathers by 20-21. When you marry so young, u ended up fucking around a few years later, thus many of these women became single-mum before 30. Many women from these countries ended up raising kids on their own, fending for their families. Even if they don't divorce, the men ended up gambling, whoring, drinking and wait for the women to bring money home (OFW).
because of their baggage, women from these countries are more submissive, gentle and pleasing to their new partners when they are in their 30s and 40s.
