Shweta, being guy, I don't think about guys in that respect. Therefore I didn't make my observation known.
But it is true that ugly people in general are also ugly inside, be it a guy or a girl.
My theory based on observation is still the same. Most Ugly women are also ugly inside too. Specially when they come to Western countries, their insecurities and jealousies comes out fully. These ugly women try to hold on to their husbands.
Now what kind of men would marry an ugly woman?
My observation
let us assume it is a jat man)
1. This jat's may have been married before to a pretty woman. And somehow he got divorced or his wife ran away with someone else. With busy life in the West, I have seen that happen in a case. To simplify let us say now this jat guy is divorced.
With some negativity associated with the label of a divorcee this jat guy has hard time finding a pretty jat woman.
So his options are limited.
Therefore he only manages to find an ugly jat woman whose family wants her to get married to a divorced guy because they want her to live a good life in the West.
This jat guy can't get over the fact that his first wife was pretty and the present wife is ugly.
then after marriage!!! he finds out that his ugly wife is also ugly from inside!!
The ugly wife knows the facts very soon.
To hold on to him she tries manipulating him in different ways like downplaying the importance of beauty, passing negative discouraging remarks against pretty women.
Slowly the ugly woman also tries to expands her boundaries of control by trying to discourage other young unmarried men making negative remarks against other pretty women, or in many different other ways.
This guy is basically messesd up now mentally.
If he divorces this one, who is he going to marry?
Now he is clever at hiding this from people who don't know him fully.
He is misreable, pathetic and wants others to feel that too.
For him there is nowhere to go!!!
2. This jat guy would be say less educated with less earning power, he may be handsome though. He may marry an ugly woman because she is far more educated then him and has more earning power. So basically he would marry her for her abilities to earn money!!
But he will soon realize that the ugly woman is uglier inside and that she demands complete control of family affairs. of course she will feel insecurity because of her poor looks and will try to discourage her husband's roving eyes. The husband may realize that he got a bad deal and now he can't get out of it!!! So they both live a life of lies.
Now suppose men in both examples have children with their ugly women. They have basically no way out of their misreable lifes.
Therefore my observation is that most ugly women are ugly from inside too and they not only make lives of their husbands miserable but other people too.

And in case you arent able to do that then ask yourself 'Who is ugly???'
