I'm so sorry this is happening to you. But like you said, you did it before you can do it again. It will never cease to amaze me how the addict can out and out lie even when the truth is staring them in the face (like her shirt).
Stay strong, I'll say a prayer for you and her. Hopefully, like you said, it's early and maybe she won't have to fall so hard before she gets it.
