Well, I have read all the posts here and I am surprised at the number of you who said they are sure they would stay together, no matter, after SRS.
In reality, the number of married couples who actually DO manage to stay together after SRS is extremely rare. This is a HUGE dealbreaker for almost all couples. It's all very easy for us to say that nothing would change if we were to become women, but in reality, asking a spouse to become, or at least appear to become, a lesbian in the eyes of her friends, her family, and all the world, is almost an impossible request.
Imagine this, here you are, destroying her husband (esentially killing the man she loved and married), and now she has to completely change her sexual orientation from heterosexual to homosexual. Homosexuals are born gay, it's not a choice, but you are asking her to choose to become a lesbian, if not in actual fact, at least to appear to everyone else as a lesbian. It's not an easy task.
There is no question but that some couples do manage to remain together. I personally have that as my own goal. But it's not an easy road and this question deserves more than the glib answer that love conquers all. Saying that if you really love each other, of course you will remain together, is, to judge by the history, extremely unrealistic.
