Hi Ranger, sorry to read about your situation. I'm sure there are many of us on here who have made the same mistakes as you - I certainly have. Don't punish yourself though, pick yourself back up off the floor and move on. Fortunately, most Filipina's are honest, genuine, loving and loyal. Don't let one bad experience put you off the whole race, there is good and bad in all nationalities, and you could have just as easily been fooled by a western girl.
I had 8 or 9 months of mistrusting my ex-Fili g/f, the writing was on the wall from day 1, but I couldn't see it, instead I kept on hoping and praying that I was just being paranoid and it would all be ok. Looking back it's easy to see what my mistakes were, and if that situation ever arises again I will follow my gut instinct and finish it immediately. Life is too short to be messed around with and let anyone play with your heart. There are lots of good girls out there who will treat you right. I've been with my current Fili for 5 months, she is the complete opposite of my ex, and I have never had reason to doubt or not trust her, something which is vital in a LDR.
Cut off all support now, and don't look back, no matter how hard it is - very best of luck to you
