I see that as a toxic relationship, just as you said. My suggestion is to stay away, completely, at least for quite awhile. I had to remove some people from my life, not alcoholics, but people who triggered my anxiety and who were full of negativity. I simply couldn't handle it, and knew instinctively they had to go. The amazing thing is, that almost immediately, two super women appeared in my life, both of who were guides and mentors to me. Without those two women, I wouldn't be where I am now, but I had to make space for them, in my life.
