First of all, if you are going to talk to your friend, remember that its all in the delivery. Obviously he loves her and will probably be defensive of her, so don't attack. Something like "Hey, I've heard those stories about Danielle and as your friend, I'm concerned about what you may be getting into." Not - "I can't believe your marrying that pathological lying slut".

More important, is that if she ISN'T pregnant right now, the chances of her becoming pregnant are pretty good since he'll think there is no reason to use birth control. So, if there is no REAL reason to bind them together now, there definatly could be soon.

And how close are you to your boss? If she says she can only work one day a week because of her illness, could your boss ask for a doctor's note? That could be your proof right there.
