It is a mixture of many things including but not limited to:
* sexist attitude about men's looks and gender roles
* chauvinistic attitude protecting female entitlements
* paranoia that it will lead to homosexuality and sex change
* guilt about living with a "sinful or perverted "partner
* public shame and loss of face
* public outing threatening family income
* lack of knowledge and help resources
* inability to share with friends to release emotions
* breakdown in trust
* financial implications of second wardrobe
* confusion over sexual roles and thoughts of lesbianism
* lower self-esteem that her femininity is insufficient
* inability to compete with the CD's alter ego
Mix the above ingredients in a large bowl and you get a person who oscillates between feelings of anger, hurt, betrayal, confusion, fear and isolation.
