would u alllow ur husband to cheat?

So if I am a woman who is not so 'good looking' cause that is how Allah made me and my two cents worth husband started cheating on me and flirting with a more desirable woman, is that my fault, would that be my azmaaish?

Just for the argument sake, if a woman wins over someones husband, dont you think that would be a great boost to her self esteem. Lets not bring self resepct cause if the guy is sleeping with another woman, that does not say a lot about his self respect either
