Am I wrong for letting her know that I feel at this point she has to walk the walk?
Absolutely not. If she admits to having a problem and wants help, she has to do it on her own. She has to attend AA meetings on her own. She needs to get herself into counseling on her own. I’m learning, as a man, that we are the worst thing for a female alcoholic. We are always there to catch them when they stumble when what they need to do is land on their butt. I hope you have started attending Al-anon, you’ll find lots of support and ideas there.
