"Another Woman" ?

I know of a woman who let herself be the "other woman" simply because she didn't feel like she was the one morally responsible. She was single, and free to sleep with whomever she wanted. She felt that the man, as a married person, was the one who had to honor his vows, and if he chose not too, it wasn't her problem.

i think they allow to be a mistress because they fall inlove with a guy, and because of love they become selfish and don't care bout other women's feelings.

Firstly in some cases a woman may not know she is in this situation as people having affairs are prone to lying about them. There are lots of reasons. These are a few I have heard of. If they do know then there are aspects of selfishness, another persons pain is not as important to us as our own gratification. Sometimes also men lie about situations (as do women) they may present a picture of being unhappy in their situation, of wanting to leave their wife and thereby invoking sympathy in the "other woman" as well as the hope that the man will leave his wife. Some women feel sexier if they are having a relationship they shouldn't, guilt or fear of being caught adds something to it.

it is only due to some personal interests and personal benefits that such kind of women do that actualy they are mentally very week kind of womens who cannot have a strong inner and they needs some personal benefit by the easiest way by doing nothing and spoiling othey families and themselves toooo
