Wow! Well written and well said. It is as if you read my mind.
In the spirit if being fair, I talked to W on Wed to say that I feel the D's need to know. The reason: it is better to learn the truth from us then to hear gossip on the street. Sure the D's will be hurt, but in my opinion, the will have respect for having the guts to trust them with the truth.
I agree, telling them reenforces good moral values in them. I'm presenting the truth and it is in line w/my other values of integrity, honesty and respect. I'm not hiding anything from them. If I hide the truth from them, then I am saying, "You are not capable of handing this. I think less of you."
I also agree w/the "sometimes Moms & Dads don't get along" BS.
