Hi Frozen, and welcome to the forum. I'm pretty new here myself but have found this to be a great place of esh, (experience, strength, hope) knowledge, and support. Unfortunately my A has never been to rehab so I have nothing to say about that. In my humble opinion, if he is in rehab all the cards need to be on the table if he is to get the help he needs. Please don't feel guilty about it, the staff there need to know what's going on with him in order to be of the best help to him. I am concerned about your feeling of being scared. Has he been abusive in the past? Do you think he will be abusive because of your honesty? I hope you have support for YOU during this phase of your ABF's recovery. Please take care of yourself and keep us posted.
