Why some men trade their sweet pretty wifes for ugly ones???

I would like to think that most people realize a relationship cannot work based on physical beauty alone. Just because someone is pleasing to the eyes, does not mean they are a treat to be around.

Some men choose personality over looks. A lot of young guys will marry a good looking woman based solely on her looks, and then realize that her personality isn't that great. Compatability and long term stability or more important than having a pretty spouse.

because they are doom!!!

maybe that beautiful wife is not just nice to him. maybe he loves the other one more despite of the fact tha she is ugly.. maybe the man fiinds her attractive?

We don't know all the circumstances involved but for sure it's just not about beauty per se. There maybe some deeper reasons. It is difficult to believe that the guy looks to her wife just a mere commodity to be wanted and unwanted when the time comes and trade for ugly ones. The ugly ones may posess more inner beauty that the man sees lacking in her beautiful wife. That being said, a man should not leave his wife for any reason and vice versa.

cuz normally beutifull girls have every thing handed to them ugly ones learn and work for every thing ever hear the song about it? its somthing like "if you wana be happy marry and ugly girl"

Actually in marriage beauty lasts for some time but ultimately it is the mental compatibility of two persons which sustains a relationship. It is possible that a beautiful girl loses its charm when the real person in her comes to surface.When you start disliking a person even the most beautiful person does not look beautiful to you as it is rightly said that beauty lies in the eyes of beholder.
