Hi- Im not separated from my AH, but I just wanted to tell you that I know what its like to hide someone elses secret and the shame that comes along with THEIR addiction- we don't want anyone to know that our loved ones have become addicts. Its hard to keep their secret, and exhausting. A lot more people will comment on how to get through the separation, and their advice will be great for you.
If you felt you needed him out of the house then you were listening to your gut and your gut instincts never fail you. You did what was right for you and your children- never feel bad about that. Take care!
