"Control Freak"

The partial definition, pieced together from various sources, of which is:

Control freaks rarely know that they are one. They believe they are helping with their "constructive criticism" or taking over a project because "no one will do it right". They don't see their controlling behaviors as symptoms of what's really going on - their own anxieties running amok. 

In some cases, the control freak sees their constant intervention as beneficial or even necessary; this can be caused by feelings of separation or departure from one whom loved, believing that others are incapable of handling matters properly, or the fear that things will go wrong if they do not attend to every detail. 

In other cases, they may simply enjoy the feeling of power it gives them so much that they automatically try to gain control of everything and everyone around them.

Core elements of a controlling or bossy person include a lack of trust in others and their abilities, a feeling of superiority, a need to criticize and a liking of power. They tend to think they are entitled to being in charge and to bossing around others. 

If they are disrespectful, arrogant in tone, pushy and dictatorial, this is a sign that the person is controlling rather than requesting, negotiating and respecting.
