The Perfect Friend Complex is a mental disorder not really recognized by many people which makes some people feel like they always have to be a perfect friend to their friends and mates. This is usually a provoked by someone getting dumped by a group of friends too many times without being told why. That makes them anxty to know their wrong which they aren't told. Which in turn makes them always feel like they have to be Perfect to evade that from happening again.
I have been dropped by friends without being told why so many times I have developed a Perfect Friend Complex.
