I feel I am a codependent. After my recent break-up with my girlfriend, with whom I had an in and out kind of relationship for 4 years. Also, I believe she had Narcissistic Personality Disorder(NPD) traits, which I got to know now, I thought she had some emotional baggage all the time while I was with her, but once I read about NPD traits, I am sure she did had NPD. Same goes for me, I kept on bring with her, even when I knew that she didn't valued me enough, used to excuse her for her behaviour because she was disturbed perennially. Her family fixed her marriage with someone else recently. She says she can't feel for me on emotional level. I feel depressed and heartbroken and unable to let go of this feeling of being abused and used. What could be the therapy for addressing this issue.
