You ask a difficult question
You are asking us to make a judgement call on very little information, which is difficult and unwise thing for anyone to do. I am assuming you have met her on an online dating site.
If you have met her on line dating site, and never in person then you may want to heed the warning that is usually posted sayings something like "never send money." However it seems most of us have done it at some point in time.
If things move forward to may want to consider sending a plane ticket, but not money for a plane ticket. Get a ticket that is only refundable to yourself, not the passenger.
You will likely find out soon enough, but try to minimize you financial risk versus your emotional pleasures, and fantasies.
Unfortunately it takes time to find out if she is real or not. Have you ever met her in person? Seen her on a cam? Seen her on Facebook? Are you mentioned on here facebook site, or anonymous?
I would suggest you consider funding your own ticket and come and visit the Philippines if you have never been here before, and see and meet real woman of the Philippines. There are lots of nice one here.
