Help

I just left ex whom I was with for 5 years. In all the stories I have read he is a full blown narc.. Omg I FEEL so used . He was charging me 1000 rent when his house was paid off. My voice was never heard his way always he would always put me down. I also notice that he would go outside and talk to himself while smoking cigs. I must mention that his sister suffered from mental illness her entire life. Sad to say she passed away at age of 48 - 3 yrs ago , I must also mention that both his parents are descead he has no family. Guy has not worked in 12 years lives off inheritance along with the money I was paying monthly to him. He would always tell me that we would be great together if I was nicer to him!!!! I was so confused all the time I lost my self esteem. I was always a confident girl it was to good to be true. Very good looking, charming, intelligent man why would he also keep all of cards that were given to him by girls he would date and how they loved him. I know that I used to show him affection. In the beginning then came to a stop when he started to not be so nice to me..I started to have resentment towards him . It was if I could only do this or if I was a cook which I was.
Not. He always told me he was total package and I would get tired of hearing him look into the mirror and tell himself he was not bad for his age. Am sick to my stomach how could have I allowed this. Help l
