I Want to Understand Human Behavior

More specifically, possessiveness in relationships.

Whilst trying to assist a client at the office yesterday, I was taken by surprise when his fiance felt a little threatened by me for no apparent reason. What seemed like a very casual conversation quickly turned awkward. Then it got me thinking how my husband used to show such possessiveness over me. There were times when his petty jealousy would make me feel like I was some type of possession to him rather than his partner. Most of our arguments always led to him suspecting me, or accusing me with other men.
What brings about such insecurities in a relationship? What is one partner doing wrong that surfaces such feelings? Although being single can be hard at times, I wouldn't have things any other way. I hate having to answer to anyone, and spend my days fighting off baseless accusations.

I enjoy being independent on all levels.

Yeah there's a fine line between caring and irrationality. My ex never stopped me from going anywhere I wanted, he'd just be up waiting for me to come home. There were times when he didn't want me to go, but he was never stupid enough to try and stop me. lol Yeah I've been there where I had to realize some of the things I did hurt him and it was no fault of my own. I had to decide was it more important for me to behave that way or for me to not upset him.
