To resnic123.
I assume you have known your partner for some time now - 3-6 months maybe ?
Another 6 months in the UK, and you will have known/been with her for a year +.
Question: Surely if you truly loved your partner you would know within this period of time if whether or not you are both 'right' for one another ?
If you are unsure after this time then I suggest you maybe aren't ready for marriage, or have a serious commitment problem. Your lady in PI will love you and want to be with you wherever you are, in UK or the north pole it doesn't matter. Sounds like its a commitment problem to me.
