I can see why a member here says this sounds abusive.

She has isolated you from your own family, she is very controlling of you and condemning of you, she does not give anything within the relationship, and she denies you of essential needs within the relationship. Those are all characteristics of abuse.

I see you as being overly obligated and being a caretaker of someone who is in fact, harming you in many different ways - which is actually codependency. Though I am no therapist so I won’t attempt to diagnose, but often kids of alcoholic parents grow to become codependent. Did your therapist mention anything about codependency?
