Incidentally, as MadKitty brought up, he may very well have lied to the other woman. This isn't an excuse on her part--if she knows he's married, a woman is still wrong to participate in his cheating--but I'm making the point that I've seen many women who cheated, and they believe the man when he says the wife has cheated, they're not happy, they're having problems, they're getting a divorce, the wife is a B, etc. I'm not saying these things are never true, but the point is, the "other woman" often decides she can trust him, so she doesn't even check out the wife, to see if any of it's true. She shouldn't get involved with a married man, IMO, but my point is, if you're going to do it, you should find out if he's already lying to you about the most important part of cheating--the party being cheated on. Frankly, I believe, if he'll cheat on his wife, he'll cheat on you. I also believe, while the cheating is between the husband, wife, and the person(s) being cheated with, if there are children, they're victims, too.
