Who knows what's the right approach?

So for the past 8-12 months I've been operating under the belief that it's better that the boys don't know that Daddy had an affair.  The reading I've done has been pretty unanimous about that.  And then today I read this article  which says you should.  I don't know what's the right thing.  All I know is that I don't want them to grow up to do such things.  Thank God I can talk to Dr. P tomorrow.

And here's another good blog and post.
