How is functional and endagering able to go in the same sentence?
If they kids are in danger, the guy aint functioning. Here in my ciity courts, I told the family court judhe my ex is a drunk and fave testimony as to what he has done, she offered a guardian ad litem on the spot, a legal representative for my son who performs a full back ground investigation with every human being that comes into contact with the child on a daily basis.
Thats how the proof with come. I suggest you confer with a lawyer and or thereapist on your legal options. Good luck and welcome! PS...also get to alanon!
