How to say Goodbye

How do you say goodbye to someone for the last time? How do you say goodbye to someone who is still alive, yet will be dead to you? When someone moves away, or goes on a mission with low chance of survival, or in my case, breaking up with someone who can't bear to see you again out of fear of emotional turmoil, how do you proceed? Do you do it with a hug? Do you do it with kind words? Do you use words of vague hope? Do you try and provide a complacent closure to it? It's a little bit different than death, but much the same. You will never see them again, yet the person is still alive. But they might as well be dead, except for the fact that if you were desperate enough you could go see them whether the person would like it or not. I don't know how to go about it, just as I don't know how to go about death. She, on the other hand, went about it with sorrow. I had never seen such a steady stream of tears over a person in my life. It really was as if I was dying to her, because she would not want to see me afterward. She wanted to dissuade me, and part of me wanted to be dissuaded, but in the end I forced myself to stay firm and walked away. I can't tell which is more cowardly, walking away because I'm running from the problem, or staying with her because I don't want to feel the separation anxiety or want her to suffer so heavily. I can't help but daudle on it, just as I do death. What is right and wrong – what is the correct practicum to follow in the face of death – I do not know, though various religious books say various things. They say things to calm you, with promises either of a heaven or a better rebirth. Whether its true or not, it does make the experience of dying easier. In my case, I am to think there will be other girls and life will be better and more productive without this one. How can I be sure though? I acknowledge what I am reliquishing, and it is abundant and free. I honesty don't think it can get better than that. Maybe I just want a harder life. Maybe the strife is caused excites me and makes me feel alive. I don't know how I can be sure. I don't even know if I did the right thing, not to mention there is still the possbility of effectively coming back from the dead. I'll leave it at that for now.
