Great big hugs coming your way! By the sounds of things you did really well. DD is most likely overwhelmed and processing information and will probably have more questions but it's great that it's out in the open so you can keep communication lines open with her.

Please don't think like it will affect your marriage. DH needs to be understanding and open about this too.

I was told at 9 but in completely different circumstances and without open communication. Your DD sounds like she is very mature and with you by her side every step of the way she will be fine.
