hi Ady,
about her previous application of VV that was denied, I dont see it as a problem when u're planning to apply another visa soon whether it is fiancee or spouse..
when I applied VV before I also got refused and we also put there that we're friends..
but after gathering enough evidence to prove to them that we really love each other and are genuine with our intention to marry and to live together voila my fiancee visa application was granted in 5 weeks.
hope it helps..
Goodluck..
