Yeah I remember you saying that. I've had periods of sobriety too.....seems they are pretty much forgotten when I relapse. Personally it took me a while to realize just how much a normal person can't understand the power of addiction. So when I'm not drinking, a huge deal for me, it's just expected by those around me. When I relapse, something that i more easily accept, they see as a huge deal. Not sure if that makes sense.
It's hard but giving her some space is probably a good call. She knows you can do this. Maybe there's hope in the future.
