it is me or am i narcissistic?

I am simply amazed by this. Back in 2003-ish during one of the times I was "off again" from an on-again, off-again relationship, I very briefly (three weeks?) dated a guy who was also "off again" from a similar relationship. (Double rebound?) The end of this short fling occurred when he had the opportunity to be "on again" with the woman he was deeply in love with. He dumped me. No big deal, life went on with no hard feelings. We remained friendly and I even became friends with his "on again" girlfriend.

Fast forward to 2009. I ran into the rebound guy at a music festival and, logically, I went over and said hello. His less-than-warm response made me question whether he even remembered who I was. I chalked it up to the shortness of the relationship and the "longness" of his pot smoking.

Apparently, he did remember me but was upset that I didn't "fight for his affection" after he cut it off. WHAT??!!!? Really?

So let me get this straight. He was actually miffed so much because I didn't challenge his girlfriend (who I had become friends with) to try and continue a three week rebound relationship...miffed enough that he still held hard feelings SIX YEARS LATER?

All my years of studying human behavior and this one has me baffled.
