nicole5353,
Hi Nic, welcome to Sober Recovery, sorry for the circumstances that brought you here, but I guarantee if you keep reading here, and following some simple suggestions, you're going to feel better, I promise.
First, try to get to meetings a.s.a.p. If you cannot find Naranon in your area, attend Alanon.
Also, there's a wonderful book, Codependent No More" by Melody Beattie, (an oldie but a goodie) that decribes pieces and parts of us codependents.
One other thing, in your post you suggested that perhps it is or was YOUR fault that he used. That is SO not true.
For right now, decide to start working on YOU.
And, keep posting, we're all here for you, okay?
