Sorry, man. That's tough. I think the truth gently served in a portion that the kids can handle at whatever age they are is the best thing. Sounds like you did the best that could be done to me.
My boys are early 20s. One says he doesn't like it but just doesn't think about it. The other says he doesn't like it but there's nothing he can do about it.
FWIW...I told mine essentially the same thing. It's mom's decision. She has to own it and we can't control it...we can just decide how we will respond.
