Pure laziness. Taking care off long hair is alot of work. After marriage women have their man and feel they don't need to work hard to keep him...until things go bad. Women know that long hair is a turn on for most men. Some of us more than others. That's why younger women that are dating and looking for "the right man" tend to have longer hair. That's why most models and porn stars have longer hair. That's why my wife had long beautiful silky hair when I first met her. Then they figure, well, I'm not looking around any more why bother with long hair and of course their hair dresser talks them into cutting their hair short because she says "it looks good, and long hair is out of style anyway". Yes, out of style for a lazy married woman that doesn't care what her husband thinks. Funny, if my wife told me that growing a beard or shaving my head bald was a turn on and proved it to me in bed, I'd do it. I used to brush my wife's hair until it was silk and I had a hard on like you read about. The more I told her I liked her long hair, the more she cut it. But if you notice, women that have been married for a while and have always had shorter hair since marriage... all of a sudden their hair starts getting longer... guess what... 9 times out of 10 the next thing you find out is they're getting divorced and now they have to look sexy again. If my wife ever starts growing her hair long again, I'll know why.
