So what are you getting out of the relationship?
I know for me, when I finally got dead serious about my recovery from drugs/alcohol and from codependency, I began to make progress.
I saw where toxic relationships added nothing to the quality of my recovery, and I started making some very tough decisions in order to surround myself with "healthy" people.
I have never regretted the decision to stay out of toxic relationships, and my life has greatly improved in all areas.
I no longer want to be that woman who would settle for less just for the sake of having a warm body in her bed and a man in her life.
Sending you hugs of support!
