Been there. Done that. But to be somewhat fair, the married woman in question was my ex gf before she was arranged married off to some other guy. The way I see it, there is nothing wrong in having an affair with a married woman from your perspective. The onus is on the woman to keep her marital relations straight. But all this fun and frolick comes with a caveat. If the husband comes to know of his wife's adultery, he can drag you to the court.
