Can cross dressing alone really end a relationship?

But I think it's true that we tend to expect them to stick to the standard male practices and get annoyed when they don't.

This is very true. Most of us, if we are hetero, do want our chosen male partners to be male. :p

But Gendermutt referred to an ultra masculine male. I imagined the stereotypical, insensitive and brutish sort of guy. Most of the guys that I know aren't like that. They actually change their kids diapers, help do the laundry, cook some meals, get mushy when they see some movies, hold their wife's purse when she needs them to, etc.
