The thread starts with the assumption that crossdressers have to choose between their dressing and their marriage. However if you read enough life stories it is clear that it is mostly the SOs who choose between their desire not to accept their husband's crossdressing and the marriage. Usually it is the crossdresser that is trying hard to save the marriage.
So maybe the question should really be - is it really that easy for a SO to give up a marriage over her dislike for a man in a dress?
My point is there is always a flip side to every argument. At the end of the day, a marriage is two people trying to live together but ultimately each is trying to ensure their agenda, their wishes and wants takes precendence. I know a marriage is supposed to be about unselfish sacrifices and fair compromises but alas we humans are not actually built that way and we struggle to keep our selfish desires under check. Men and women are equally guilty of this. It is easy to point a finger at another but much harder to point it at ourselves.
