I do somewhat control my children's lives. One reason is because I have somewhat of an obligation to until they can totally fend for themselves. Sometimes I have to make them eat their vegatables, make them take a bath, and make them go to school.
Right now I have a situation with my husband, that I would like him to change a certain thing. However, after many months of frustration, tears, and fights, I realized that I had to give up the notion of making him do anything. Once I gave up trying to change him, and just started trying to work on myself (my reaction), I felt a lot better. He has made some changes, too, although there is a long way to go. One thing I changed was to stop sending mixed signals: bitching about his behavior, but then enabling it. I stopped both. We still discuss it, but I don't enable the behavior any more. I show my intolerance for it that way, but we don't fight any more really at least.
I think we sometimes try to control out of love, because we don't want our loved ones to be hurt, etc. Sometimes we try to control others because we want things to go our way, whether for the good or bad. As an employer, you have to have some amount of control over your employees to run the business effectively.
