Depends on the status of the man lah.
If the man has status, the woman is unlikely to divorce him. If the man boh lui, then the woman will jump on the opportunity to divorce him and can push the blame to the man. In actual fact, the woman wanted to divorce the man long long ago, but didn't want to be seen as the party breaking the marriage vows.
If the woman was a virgin at the time of marriage, then the husband's adultery will mean a lot to her, and she is more likely to see him as "dirty". But if the woman slept with other men before marriage, and had pre-marital sex with the husband before marriage, then the moral or immoral of adultery means very little to her lah.
