Hello Tommy, welcome to the site.
Sorry to hear about the refusal of the visas of your fiancee. Any idea or reasons of why she has been refused?

I think the last resort is to marry her and sort the spouse visa, this is a big steps but you worth it if you are determine.

I suggests Petes website as I found it as very relevant source; http://www.british-filipino.com/How%20to%20Marry.html

goodluck
