You have a choice. So far, you have chosen to be front row at the three-ring circus. Is that what you really want? The roller coaster analogy works because she is a ride/a drug to you. The incredible highs are followed by terrible lows. You have a choice. You choose yoru life and she chooses hers. I do understand because there are those in my life who I love who have chosen drugs. However, I can choose not to be a part of their craziness and not to have a front seat.
