our case is completely different. we lived together here in the UK this year till her student visa expired. however--there is no evidence of this.
So in reality none of that actually ever existed to the UKBA so you are starting from scratch, and she is in the Phil. So your case is no different than others who actually met online when it comes to applying for a visa.

so--if she can get a tourist--or family visa to come back for a few months--thats the time to start the clock starts ticking--amass evidence we have now met and a relationship started.
This is the problem myself and others have pointed out as it comes down to abuse of the Tourist visa and the UKBA look down on this type of thing and we have seen many Spouse visa's refused for trying to 'bend' the rules which is clearly what you will be doing even if you think otherwise. When evidence is supplied as evidence of relationship on a tourist visa it takes some explaining to the UKBA.

You can take the easy route and visit her in the Phil which results in the vast majority of visa's being issued on that evidence, or try it your way and gamble the fact the majority get refused based on the experience of others on here.

If one trip meant the difference between definitely being with the girl of your dreams for life, or a long hard struggle with the UKBA, I know what all the members on here would pick.
