X spent a year in rural China teaching English?
Came back "invigorated" did he?
I know the feeling; being awash in hot young females is very invigorating for a man.
He is ruined as far as western females are concerned.
The only reason he is looking up his old flame(LW) is that he has returned to the dried-up men's penal colony affectionately known as America. He is disoriented by the sexual disparities and needs some action soon.
Unless the LW is asian, she is history with this guy. He will run off with the first asian grad chick he can find, or simply return to Asia next time he gets the chance.
