Welcome to SR I'm a newbie to this forum as well.
Whenever ive made major life changes there has always been some necessary house cleaning. I'm a Codie (co dependent) and the more I focussing on my self and not on everyone else as I use to, some people mainly addicts don't like the new me and the new me is better able to detach from them.
IMO since your friend isn't in recovery she won't be able to listen respect or understand your needs anyway as its all about her and booze.
Just establish NC and soon enough I bet she will go find another person to cling to for drinking support.
You are amazing for making such a great life change don't let anyone or anything take that away from you.
