From a Dating Dames Reader asking for the advice:
Dear Dating Dames,

I have a close personal friend who has grown so serious over a certain girl that he’s considering proposing to her soon. I’d hoped he would find out on his own that she has cheated on him several times. That doesn’t seem to be the case and I’m afraid he’s going to get even deeper in something that will end up hurting him much worse.
Should I tell him what I know?
