If the husband was talking about sleeping with another woman at the time, who's to say he didn't do it after they were married? Perhaps he's being so nice to her now because he feels guilty for something he did wrong. I think the LW is perfectly within her right to be upset and she should confront him about what she found. I don't think the hubby deserves any sympathy, because if kids were such a "no no" then he wouldn't have dated and married the LW. If he makes a choice that's against his standards, that's his fault, not hers. I think Prudie isn't taking the problem seriously enough. Infidelity, even if it happened in the past, is nothing to brush off.
