I agree with card. Don't offer the info. If he finds out on his own and decides to come then so be it.
I understand the natural draw to help him when it comes to your D. It is hard to break a habit that you probably had during your M. It doesn't really help though because it prevents H from having to suffer the consequences of his choices. He is a big boy and if he has to go back and forth ten times because he forgot something that's what he has to do. He will also appreciate more what you did do in the home and with D. when he actually has to fend for himself.
There is a difference between being pleasant and being a doormat, I know because I have been there. Being too "nice". Be a friend to yourself first. You are teaching D what a strong woman is.

Accept what is...let go of what was and have faith in what will be.
