I was going to post tonight about my AH who has done bad things to me again this week. However, after reading about your problems I will not. You have giant problems!!! My problems are small compared to yours.
Just keep those wonderful children protected at all means!!!! Now may be your AD's bottom and I hope so for all of you. If you can have the kids that is the most important thing in world. They need to be with you at this time.
I know you love your daughter but just think back to when you were a child- a perfect and unknowing child. No child any where in this whole world should have to deal with any type of addiction!!!! Childhood is a time of such great stuff and great fun. No adult ( addict or not) has the right to rob this from a child!!!! Please do everything in your power to protect your grandchildren.
Many hugs to you!!! I hope it all works out!!!
