I suspected Narcissistic Personality Disorder in a long time friend. His behavior patterns became very noticeable during an argument with me. After that I talked to my therapist about him and the incident that made me see it more clearly. She agreed with me. He is just using me for his own purposes. It’s not a real friendship for him.

Now I am seriously thinking about terminating my friendship with him. 
I suffer from dissociative disorders. This disappointment causes a lot of stress, I am not doing well.
What annoys me the most is that I have distanced myself from wrong people in the last years, I have cleaned up, at least I thought so
