principle of least interest

On Tuesday we talked briefly about the principle of least interest and how it was a very important component of influence. A few weeks ago my boyfriend and I were having problems and I was talking to my roommate about it and she mentioned the principle and asked if I had heard of it because that sounded like it fit part of my problem. I was the one who was the least emotionally invested in the relationship so I had the most power. I could influence my boyfriend to do whatever I wanted and part of that is his personality but I think also part of it was because he was afraid to lose me. I was unconscious of this power holding for a long time and I don't remember ever using it in a malicious way. Looking back, I think this seems to be the trend for my past few relationships and maybe part of the reason I ended them. I think it's important for people to realize if one person is more powerful and why that person seems to have more influence over the other so if there is a problem or imbalance, you can efficiently resolve it.
