Do short guys have what they call a "short complex?"?

I'm 5'6" and my boyfriend is 5'4". He seems to have what they call the short complex. He used to always want to fight everyone like he had something to prove. He used to try to be this tough guy. Nowadays he is more laid back, but he gets these stupid little attitudes about nothing, he gets real jealous and thinks every man is a threat and trying to holler at me. Tall guys I've dated never seemed to behave this way. His height didn't used to be a problem to me, but the uglier he acts personalitywise, the more I start to find his height unattractive. Do most short guys have this mentality?
