I think your problem will be convincing ukvi of your 2 year relationship being genuine. Using your preferred option gives ukvi too many loopholes to refuse...and believe me they will if they can. Dont get me wrong..i think your genuine..but i,m not the one reading your application. They will want to see written proof of living together..a paper trail in fact. Joint bank accounts with both your salaries being paid in..and each of you accessing the account. Any joint bills ? Letters and invoices addressed to each..and both, of you at the same address, evenly spread over the 2 years of you living together. Joint property ownership would certainly be in your favour...only problem being..you..as a foreigner cant own property in the philis ! How does all this stack up so far ?
