I was starting to feel a bit of a fraud being here, and I also find it very hard to comment on anyone else's post in case I 'taint' them with my non-DB attitude...
I don't think you have a non-DB attitude at all! You want a close friendship with your H, a good co-parenting relationship with him, all of that is right in line DB, IMHO.
I hope you know that your forgiveness & strength through dealing with the fallout of your husband's SA was a huge inspiration to me when I felt weak, so you are very, very far from a DB fraud!
