hi
it sounds like you have made things a little more complicated than you needed to i would suggest if its possible to pay the charges if possible for overstaying then at least that will partly restore the situation where your living now
if thats done im sure that you can apply for the fiancee visa into the uk
once all your documents are in order if you cant then if your willing to return to philippines then a visa can be applied for there more easily providing you have no problems there
i would suggest you go to the embassy in manilla direct yourself it can be a bit scary there is no need to use the services or many so called agencies there in philippines they charge a fortune often for very little in return once you have got the application form and paid the fees it is far less scary than you may realise i do believe you will need various checks made in philippines as to your records there ie police etc
obviously if your already married by then it would be more likely you wont have issues with the fiancee visa
do not submit any docs that are fake which can be easily obtained there any doubts wait until everything is in order
i do know a little about the process the scammers fixers visa agents from experience
good luck best wishes mark
