Did 'nice' things such as volunteered at homeless charity on Christmas Day (for the sole purpose of telling everybody about it/announcing on Facebook for likes and so everybody would say how kind he was)
Played the victim, nothing was his fault. He would have a sad puppy dog look that would make people including myself feel sorry for him until I realised his version of events were basically made up
Attention seeking but not in a show off way like look at my nice car, but more look at this creative project I've done, look at this nice thing I've done for someone, look at me, me, me, me and was so obsessed with curating his image to looking like a nice guy (but he was anything but underneath the surface)
Once I got to know him, I thought he'd be a kind, interesting individual and was disappointed to find out, all he cared about was his own self promotion. He cared nothing for anybody else, was incapable of listening (apart from in the love bombing phase which was intense) and was so me, me, me. It was incredibly draining.
Held grudges against people, e.g. work colleagues who may have done something most reasonable people would find minor, e.g. disagreed with something he said in a work meeting but he hated these people years later, and got visibly angry talking about them.
Liked to tell everyone and I mean everyone about how depressed he has been in the past- including people he literally had just met, all for sympathy- very woe is me.
I could go on and on, but he was exhausting and it was quite traumatic untagling what had gone on, as on the surface he seemed a wonderful kind and genuine man. But he was actually soooo narcisistic and cared so mcuh about preserving his very highly curated appearance online and offline.
