It is always fun to try or get something new. There is a feeling of cleanness, of excitement, of inspiration. Probably a false sense of starting over with the proverbial clean slate.
Later on in my life, I had to recognize that this emotional rush can be a deadly addiction. As a child and young adult I was never taught how to engage in healthy relationships. There was always a sense that if things didn't work out, you cut that person out of your life or you relocated physically. Although you had the excitement of new things, I have to admit that there was always a hidden sense of pain. I am reminded of the "Golden Compass" and the use of cutting to remove your soul from your body. Life without a healthy perspective on friendship and family can result in the same torn fragments.
It has taken me many years but I have come to learn what healthy interaction looks like. Sometimes you don't agree, sometimes you have opposing views, sometimes you are on the same wave length. Such is life and life is meant to be lived, not constantly run away from.
So although I have several "new" things in my life right now, I cherish the "old". The safety and security that comes from knowing you worked hard at a relationship brings abundant peace.
