It's just that in my opinion doesn't sound right.
"My Filipina"....
"My Filipina wife", would sound much better, and correct.
I may just be nitpicking, but to me it is wrong. It is like describing an object, my car, my house, my hammer. etc.
I would never introduce Jet, as "My Filipina"....
Or refeer to her as that.
My two pence only, don't take umbrage.
