Yes, in this case, demand. Demanding doesn't mean screaming and yelling, demanding means that (if I were her in this situation) I will not be a part of an extramarital affair and that the marriage must be dissolved before I would even consider being romantically involved with the man.
"The hungry don't get fed" What the heck does that mean? There's nothing wrong with wanting a person's marriage to another person to be over before getting involved with them. That's called setting boundaries for a relationship. I demand that my husband not sleep with other women, does that make me a psychotic nut? No, it does not. He demands that I not sleep with other men, does that make him psychotic? No, that is a boundary in our marriage! We do not sleep with other people.
Not getting involved with a married man is something *I* believe strongly in. If someone else doesn't mind being the "other woman", so be it. That's their choice and their life to live. The individual was asking for advice, and I gave my take on it. They are free to listen to it or not.
