My brother's friend has a vietnamese girlfriend, and he also has a family.
Though, she knows he has a wife but she didn't want to leave him.
He has been sending money to her regularly, because he thinks she is poor and wants to help her.
I heard that many vietnamese woman (especially those are poor) like to know foreign boyfriend to get them out from poverty, is that true ? Even though, the man maybe married , they'll still cling on them.
