@imnervous30 If you mean by "Filipino Way", like any asians, you need to pay your respects to her family and even spend time with family, when you say family in the Philippines, that is like a whole community since Filipinos are family oriented. Nothing fancy when you deal with a Filipina since they are culturally reserved and independent. As long as you deal with the family in a nice way and respect her beliefs and be understanding - and above all, you get along. Just pop the question!
if you want it extra special, better say it secretly to her siblings, cousins and they might be your help to give a memorable proposal.
