bumtwo, I have no experience with that type of thing. But my 23 yr old daughter does.
Her fiance snorted oxy, she had no idea. She just thought he was becoming mentally ill, took him to psychiatrists etc....
He began hallucinating, seeing people that weren't there, seeing spaceships flying out of the fridge etc. He eventually lost his state job when drug tested, this is when she found out his mental illness was oxycodone.
Until you make a decision.....
I would recommend you NEVER NEVER leave your son alone w/ your AH.
I would recommend he not sleep in the same bed.
When and if you decide, which I hope you do...Family Court is always an option to get a restraining order, custody, and child support.
You should NEVER have to live in that kind of fear.
Hoping the best for you and child. How old is your child?
