So does their moving away, changing jobs, marrying someone who hates your guts -- Changing cultures, clubs, beliefs, groups, or sexual preference: Yes even gaining or losing weight. Addictions: alcohol, drugs, gambling, to me are simply slow suicide: People who don't want to live life: And the impact on friends, family, and even strangers is both often worse and far more prolonged than the suicide who simply gets it over with.
At what point do you tell them, "This is not your life to live. What you do impacts me, therefore I have a say in what you do with your life."? And at what point do you tell them, "You choices are yours. You have to live with them and so do I."?
I remember an adult woman with children of her own: Her brother called her and informed her their parents were getting divorced. He said, "You have to do something. They will listen to you." The brother had left home and was in college.
She told them if they loved her they would stay together because if they divorced she would kill herself.
None of this is about love -- It is about control. Who gets to control whom, how, and why. Suicide is also about control. So are many other negative things in our lives.
Perhaps if we spent more time loving each other and less time trying to control each other there might be fewer negative things in our lives and fewer reasons for them.
Too bad, but I don't tell other people what to do with their lives and I don't allow them to tell me what to do with mine.
