But for right now, at her request to xah, the kids are with me and only seeing their dad for supervised visits. And I am grateful for that support.
My question is how to move back toward 50%50% custody again.
I am sorry for your dilemma but I think you are wise to give this some serious thought and put the children first.
For now I think supervised visits may be wise. You could discuss this with the kids and you may be surprised that they will feel safer too. Children simply are not safe in a home where addiction and drugs exist.
I think 50/50 custody is a bad idea right now, he has shown you all that his addiction comes first, even if it is spaced out and not frequent. It would only take one bad incident to ruin the life of one of your children.
Sitting down and discussing this all with them is a good idea too. They may know more than they are telling, feeling somewhat "in the middle" and need to have someone they trust to tell the truth to.
I hope you can make a safe arrangement that works for the children and you, as well.
Hugs
