The term soulmate is being thrown around a lot the last couple of days at TRF
In the Monaco forums, people are questioning on whether or not Charlene is Albert's true soul mate (and she is coming up short in the poll) and over at the British forums, pretty much a majority of people think that Sarah is Andrew's soulmate.
And here is how it comes out:
Albert & Charlene - not soulmates according to a majority and who are scheduled to marry but shouldn't
Andrew & Sarah - soulmates accordign to a majority most likely not to marry because of Sarah's issues (you can take it anyway you want) but really should.
Not to go off topic but it should be VERY interesting to see how the two couples play out.
