Doing ok today, kept busy

Went to church, then lunch and a movie with a friend and her family.  Was not sure I wanted to get out today but so glad I did.  Hard part was going to the theatre my ex and I always went to and also driving home through his old territory.  I miss him so much!    
Wrote down negative things about him which somehow helps.  He's horrible with money and has really bad credit.  He never built a relationship with my kids in 4 years.  He is a friend to his kids more than a Dad.  He runs when too much responsibility is put on him.  All these things I felt ok with because they were not daily issues.   Now I look back at his stories of past girlfriends and ex wife.  He is not one to let go of his past easily.  He separated with his ex wife 3-4 times before they divorced, and 2-3 times with a girlfriend he had a few years later.  I don't think he has ever lived on his own but one time and it was not for very long.  
I was married 16 years before meeting this current possibly ex boyfriend.   We tried marriage counseling and I was the only one trying.  Counselor said he had narcissistic personality disorder and would even say this in court and that I was severely abused mentally.  Almost 5 years later, he still believes I am the cause for our divorce even though he was having affairs and was addicted to porn.    I saw a counselor for a short time after the separation finally happened and I couldn't even tell her what "I" enjoyed doing for myself, or what kind of music "I" liked, or what would I do if I got a job and had a career.   I just enjoyed taking care of everyone.  That was my job and what I enjoyed.  My brain could not comprehend anything else.
Boyfriend and I got together a year later after separation which was only a few weeks after the divorce finally happened.  Maybe I put myself right back into a similar relationship.  My daughter said he's ok but lately, he's had a "God Complex".  He demanded respect from us all, but did not do the same for us.   Is this my fault because I never set boundaries on what I wanted?   Would we have been together so long if I had set boundaries to begin with?    I respected his boundaries. 
How can I see all these negatives and still miss him so damn much and want him back?    
.....ok, back to the serenity prayer for me
