Philippines: the land of deceptive woman.?

[Kev]

Most woman in the Philippines are highly educated, caring and family orientated but, there are a segment or type of pinay girl who will devote their life to marrying a foreign man but all the while she will have a Philippine bf back who she may pretend is her cousin or brother. I'm 34 and been married to my Filipina wife for 8 years. Up until now she as decided to still live in the Philippines. I found out she was in a clan and had secret profile on Facebook. I also found out she dated a guy from the clan and dated 3 other guys I know about. The thing is, we have twins and I can't leave her because of them. I did suggest we separate but stay amicable for the kids but she said she would kill herself if I left. Why are SOME pinay so deceptive to their foreign husbands?
