Maybe someone can help somewhat determine what this person I'm about to talk about has…
I've been working with this guy for the past 7 years, over time he has changed personality wise to the point where any issue he seems to have in his life, he tries to drag others down with him as well.
For example, the guy is 5'5", not exactly tall, but he is a bit taller than my 5'3" height. A few years ago after his girlfriend cheated on him, he would begin to exhibit this trait and have ideas about how it has to be possible to genetically modify oneself to grow taller. He deemed himself "undesirable" and began to deem me even more "undesirable" due to my height.
Once he got over this issue, and found a girlfriend, he still had this idea that him and her were not compatible because he learned she was 5'7" compared to his 5'5". So he came to me and was telling me that at least he isn't as short as me. I never really let this stuff get to me.
Now it seems his dilemma is about his girlfriend cheating on him like his ex did. And since I don't have a girlfriend currently, he brings stuff up about human nature and how the chance of me being cheated on is high, and how he hopes that I get a girlfriend soon so that I too can "experience the sting of infidelity".
Do you feel that he is just pushing his issues onto me? If so, why would that be? I tried to figure him out and it seems that he can be narcissistic in a way.
