Ok a few things
When you met her did you meet her friends and family? I doubt you would meet them all as Phill familes and social networks can be huge but did you?
With Facebook has she had the account for long what friends and family are on her account? Most young Filipinas (even the wifes aunts Maids Daughter who lives in a shack with no leccy has an account with hundreds of friends) will have an account which they will use regularly did it seem the usual suspects were on there ie her best friends brothers sisters possibly parents or hi tech aunts or uncles?
What im getting at is did she seem to announce you to everyone back there that is not saying for definte it means no issues but a good indicator..
You do need a lot of trust its possible she got ill and some of the meds in phill are not the best from experience..
She may well also be a little navie and possibly found this guy she thought was just an employer tried it on and she possibly maybe felt quite upset and embrassed due to that.
I would be wary but it does seem odd to mention a guy if a "love rival" but Sars and other Filipinas have and can explain the Pinay thought processes a 100 percent better than i ever could.
Your mind will be racing and she will have lots of doubts and worries. Remeber if she gets Visa she will have to enter an alien world away from the world she has known all her life where traveling to the nearest big town/city possibly was a massive adventure..
