I prefer being this way. I recognize where it comes from --- parenting. I grew up with a mother who instilled in me that people are not to be trusted, they're messy, always want something from you, etc.
During and after my divorce, I went to therapy where I worked through some of that. Unfortunately, I have found that my mother was not totally off base...she just went overboard with it. I now recognize when that programming is at work and decide what to do from there.
I see people everyday who are stressed, upset and make poor decisions because of the feelings they've attached to a person or situation. Do I have feelings? Sure. I just choose not to wallow in them or make poor decisions based on them. If I'm sad, I cry (alone, at home where it's appropriate) and then I find a solution and move on.
So, I feel safer to an extent because I know I have the capacity to walk away from a situation that doesn't serve me regardless of what emotions are there. I just make sure to examine those feelings first to ensure I'm not just walking away solely out of fear.
