Your younger D has an advantage with an older sibling that has been through it and may have some wisdom to offer. it depends on them, how close they are etc.

My oldest has never said anything about it to speak of. Some of her friends have asked me (I have acknowledged we are seperated, but that's it), as she doesn't talk with them about it either.

My youngest has really struggled. She see's a C and she's doing alot better in some ways.

Like you, mine doesn't tell me anything. What's difficult is that he doesn't invited his D's into his life either. I'm hoping that somehow D's can have the R they would like to have with him at some point. Right now, there is little to no interest in seeing him at all and because of their ages, I let them choose. if he feels he needs to do something differently, I guess that's when he will.
