Thanks for your advice guys.

I am in a position where I am able to say provide evidence of,

-Somewhere to Live
-Stable Job with decent income
-Savings Account
-All Proof of contact with her via email, phone etc.

So I suppose its not looking as bad as I first feared.

If she was to come over on a Fiancee Visa and we didnt get married within 6 Months and I right in thinking she can apply for a 2 year extension or do we need to be married for that to happen?
