Should also add he is fine and got taken care of but I am just scared
I don't know that they will take the child, but they will likely do an investigation and may have some required recommendations for you. Try to look at it from the child protection standpoint. It doesn't matter if he actually shot up in front of her. His drug use put the child in a traumatic situation, not to mention if he is a supervising parent and overdosed while in the company of a child, that's a concern. How old is your daughter btw?
Hopefully this will put a little more pressure on your BF to get more help.
Best of luck to you.
