You know what you know no matter how much you wish you didn’t know it.
You know that he didn’t complete his rehab, you know he’s not working any kind of a program. You know that if quitting heroine was that easy he wouldn’t be an addict.
You know in your heart what he is doing what ever that is, heroine, crack that it’s not acceptable to you.
I fully agree with legna, you had to pretend to be asleep, didn’t want to deal with him or what ever reason – that is not a healthy way to have to live.
Not sure what kind of help you are seeking because even if you know for sure he is cooking crack what are you going to do about that? Will you accept that he is not ready to give it up and that your only salvation from misery and un-trust is to leave the situation?
