<human>: Is there a term for when one person in a relationship is attracted to an overly affectionate, emotionally manipulative, and unstable person?

Short backstory: I was in an emotionally devoid relationship for 12 years, starting when I was 17.  About a year after I divorced my husband I started dating someone who was severely emotionally unstable.  He is insecure, has physical and verbal abusive outburst, is a very heavy drinker, and is emotionally manipulative.  I am very attracted to him because he is very affectionate and wants/needs to see me all the time. I have a desperate need to feel loved and wanted.

I am trying to figure out how to describe this type of relationship.  I looked up the definition of codependency, but it doesn't fit.  Does anyone know what to call this type of relationship?

Summarize the given text in a few sentences.
