I'm tired of him living rent-free in my head!

I've been NC for several months and have a lot of good things in my life, including a darling new non-narc, fun, drama-free boyfriend, a successful grown child and a business I'm building with great partners - men who value and respect me.

I still think about his sorry ass all the time! It is interfering with my business because he's in my head and I'm still reading about men like him/PDs all the time. Sometimes I wonder if a final conversation would help since I ended the r/s of several years by just going NC. Trust me, I know it isn't a good idea and closure is something I have to give myself. It just feels so strange to have things end as they did. I feel like I'm always waiting for the proverbial other shoe to drop.

I know he can't be fixed but what am I trying to reconcile? Is it the anger at him for deceiving me and disrespecting my boundaries? At myself for letting my expectations be managed down and letting him back in after I knew better? I know and my nearest and dearest agree that it's understandable that it takes quite a while after the end of a LTR for the thoughts to process. I'm just so tired of the ongoing thoughts of him and ready to look forward not backward without this Narc hangover... Any suggestions?
