hmmm, my mum knows a married couple where the man became a woman, and they are currently still together, but I have heard the real woman finds it difficult, and seeing as she's not a lesbian I doubt she's happy - in this case I think they will either just break up completely, or drift into a horrible non-loving state and stay there. Of course I'm sure there must be lots of different scenarios and outcomes, but I'd be inclined to think that most of the time these relationships wouldn't work out... unless you're bisexual.
